| c29177d | Noralf Trønnes | 23 September 2016, 02:54:27 UTC | i2c: bcm2835: Add support for Repeated Start Condition Documentation/i2c/i2c-protocol states that Combined transactions should separate messages with a Start bit and end the whole transaction with a Stop bit. This patch adds support for issuing only a Start between messages instead of a Stop followed by a Start. This implementation differs from downstream i2c-bcm2708 in 2 respects: - it uses an interrupt to detect that the transfer is active instead of using polling. There is no interrupt for Transfer Active, but by not prefilling the FIFO it's possible to use the TXW interrupt. - when resetting/disabling the controller between transfers it writes CLEAR to the control register instead of just zero. Using just zero gave many errors. This might be the reason why downstream had to disable this feature and make it available with a module parameter. I have run thousands of transfers to a DS1307 (rtc), MMA8451 (accel) and AT24C32 (eeprom) in parallel without problems.

Documentation/i2c/i2c-protocol states that all of the message is sent: I2C_M_IGNORE_NAK: Normally message is interrupted immediately if there is [NA] from the client. Setting this flag treats any [NA] as [A], and all of message is sent. From the BCM2835 ARM Peripherals datasheet: The ERR field is set when the slave fails to acknowledge either its address or a data byte written to it. So when the controller doesn't receive an ack, it sets ERR and raises an interrupt. In other words, the whole message is not sent.

Which amounts to a lot for a 4k write. This is due to the fact that the chip doesn't respond during it's internal write cycle when the at24 driver tries and retries the next write.

In this case the controller has to be disabled and the transfer completed to avoid hang. (CLKT | ERR) and DONE interrupts are completed in their own paths, and the controller is disabled in the transfer function after completion. Unite the code paths and do disabling inside the interrupt routine. Clear interrupt status bits in the united completion path instead of trying to do it on every interrupt which isn't necessary. Only CLKT, ERR and DONE can be cleared that way. Add the status value to the error value in case of TXW/RXR errors to distinguish them from the other S_LEN error.

| b409033 | Noralf Trønnes | 17 September 2016, 13:07:10 UTC | i2c: bcm2835: Fix hang for writing messages larger than 16 bytes Writing messages larger than the FIFO size results in a hang, rendering the machine unusable. This is because the RXD status flag is set on the first interrupt which results in bcm2835_drain_rxfifo() stealing bytes from the buffer. The controller continues to trigger interrupts waiting for the missing bytes, but bcm2835_fill_txfifo() has none to give. In this situation wait_for_completion_timeout() apparently is unable to stop the madness. The BCM2835 ARM Peripherals datasheet has this to say about the flags: TXD: is set when the FIFO has space for at least one byte of data. RXD: is set when the FIFO contains at least one byte of data. TXW: is set during a write transfer and the FIFO is less than full. RXR: is set during a read transfer and the FIFO is or more full. Implementing the logic from the downstream i2c-bcm2708 driver solved the hang problem.

| 8852ca7 | Pantelis Antoniou | 03 December 2014, 11:23:28 UTC | OF: DT-Overlay configfs interface This is a port of Pantelis Antoniou's v3 port that makes use of the new upstreamed configfs support for binary attributes. Original commit message: Add a runtime interface to using configfs for generic device tree overlay usage. With it its possible to use device tree overlays without having to use a per-platform overlay manager. Please see Documentation/devicetree/configfs-overlays.txt for more info. Changes since v2: - Removed ifdef CONFIG_OF_OVERLAY (since for now it's required) - Created a documentation entry - Slight rewording in Kconfig Changes since v1: - of_resolve() -> of_resolve_phandles().

This patch adds headphone and microphone capability to the Audio Injector sound card. The patch also sets the bit clock ratio for use in the bcm2835-i2s driver. The bcm2835-i2s can't handle an 8 kHz sample rate when the bit clock is at 12 MHz because its register is only 10 bits wide which can't represent the ch2 offset of 1508.

At 192kHz only 128xfs is supported. The existing driver selects 128xfs automatically for some lower samples rates. By using an additional mclk_div divider, it is now possible to control the behaviour. This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It should allow lower jitter and better signal quality. The behavior has to be controlled by the sound card driver, because some sample frequency share the same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only difference is the MCLK divider. This also added support for 32bit data. Signed-off-by: Daniel Matuschek <daniel@matuschek.net> | 08 January 2017, 11:40:05 UTC |

| f6219b5 | Harm Hanemaaijer | 20 June 2013, 18:21:39 UTC | Speed up console framebuffer imageblit function Especially on platforms with a slower CPU but a relatively high framebuffer fill bandwidth, like current ARM devices, the existing console monochrome imageblit function used to draw console text is suboptimal for common pixel depths such as 16bpp and 32bpp. The existing code is quite general and can deal with several pixel depths. By creating special case functions for 16bpp and 32bpp, by far the most common pixel formats used on modern systems, a significant speed-up is attained which can be readily felt on ARM-based devices like the Raspberry Pi and the Allwinner platform, but should help any platform using the fb layer. The special case functions allow constant folding, eliminating a number of instructions including divide operations, and allow the use of an unrolled loop, eliminating instructions with a variable shift size, reducing source memory access instructions, and eliminating excessive branching. These unrolled loops also allow much better code optimization by the C compiler. The code that selects which optimized variant is used is also simplified, eliminating integer divide instructions. The speed-up, measured by timing 'cat file.txt' in the console, varies between 40% and 70%, when testing on the Raspberry Pi and Allwinner ARM-based platforms, depending on font size and the pixel depth, with the greater benefit for 32bpp. Signed-off-by: Harm Hanemaaijer <fgenfb@yahoo.com> | 08 January 2017, 11:39:55 UTC |

As a result, overrides (parameters) must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB. mmc-overlay.dts (that switches back to the original mmc sdcard driver) is the only overlay violating that rule, and this patch fixes it. bcm270x_dt: Use the sdhost MMC controller by default The "mmc" overlay reverts to using the other controller. squash: Add cprman to dt BCM270X_DT: Use clk_core for I2C interfaces | 08 January 2017, 11:39:49 UTC |

| d9edb91 | Phil Elwell | 11 May 2015, 08:00:42 UTC | scripts: Add mkknlimg and knlinfo scripts from tools repo The Raspberry Pi firmware looks for a trailer on the kernel image to determine whether it was compiled with Device Tree support enabled. If the firmware finds a kernel without this trailer, or which has a trailer indicating that it isn't DT-capable, it disables DT support and reverts to using ATAGs. The mkknlimg utility adds that trailer, having first analysed the image to look for signs of DT support and the kernel version string. knlinfo displays the contents of the trailer in the given kernel image. scripts/mkknlimg: Add support for ARCH_BCM2835 Add a new trailer field indicating whether this is an ARCH_BCM2835 build, as opposed to MACH_BCM2708/9. If the loader finds this flag is set it changes the default base dtb file name from bcm270x... to bcm283y... Also update knlinfo to show the status of the field. scripts/mkknlimg: Improve ARCH_BCM2835 detection The board support code contains sufficient strings to be able to distinguish 2708 vs. 2835 builds, so remove the check for bcm2835-pm-wdt which could exist in either. Also, since the canned configuration is no longer built in (it's a module), remove the config string checking. See: https://github.com/raspberrypi/linux/issues/1157 scripts: Multi-platform support for mkknlimg and knlinfo The firmware uses tags in the kernel trailer to choose which dtb file to load. Current firmware loads bcm2835-*.dtb if the '283x' tag is true, otherwise it loads bcm270*.dtb. This scheme breaks if an image supports multiple platforms. This patch adds '270X' and '283X' tags to indicate support for RPi and upstream platforms, respectively. '283x' (note lower case 'x') is left for old firmware, and is only set if the image only supports upstream builds. scripts/mkknlimg: Append a trailer for all input Now that the firmware assumes an unsigned kernel is DT-capable, it is helpful to be able to mark a kernel as being non-DT-capable.
