soc: bcm2835: sync firmware properties with downstream

2019-01-09T15:34:46Z

Add latest firmware property tags from the latest Raspberry Pi downstream kernel. This is needed to use the reboot notify in the following commit. Signed-off-by: Stefan Wahren Reviewed-by: Eric Anholt

ARM: bcm2835: Add GET_THROTTLED firmware property

2018-06-22T00:17:11Z

Recent Raspberry Pi firmware provides a mailbox property to detect under-voltage conditions. Here is the current definition. The u32 value returned by the firmware is divided into 2 parts: - lower 16-bits are the live value - upper 16-bits are the history or sticky value Bits: 0: undervoltage 1: arm frequency capped 2: currently throttled 16: undervoltage has occurred 17: arm frequency capped has occurred 18: throttling has occurred Signed-off-by: Stefan Wahren Signed-off-by: Eric Anholt Reviewed-by: Eric Anholt

soc: bcm2835: Make !RASPBERRYPI_FIRMWARE dummies return failure

2018-04-16T22:15:23Z

If CONFIG_RASPBERRYPI_FIRMWARE=n: drivers/gpio/gpio-raspberrypi-exp.c: In function ‘rpi_exp_gpio_get_polarity’: drivers/gpio/gpio-raspberrypi-exp.c:71: warning: ‘get.polarity’ is used uninitialized in this function drivers/gpio/gpio-raspberrypi-exp.c: In function ‘rpi_exp_gpio_get_direction’: drivers/gpio/gpio-raspberrypi-exp.c:150: warning: ‘get.direction’ is used uninitialized in this function The dummy firmware interface functions return 0, which means success, causing subsequent code to make use of the never initialized output parameter. Fix this by making the dummy functions return an error code (-ENOSYS) instead. Note that this assumes the firmware always fills in the requested data in the CONFIG_RASPBERRYPI_FIRMWARE=y case.

Add latest firmware property tags from the latest Raspberry Pi downstream kernel. This is needed for the GPIO tags, so we can control the GPIO multiplexor lines. Acked-by: Stefan Wahren Signed-off-by: Baruch Siach Signed-off-by: Linus Walleij

staging: vc04_services: fix up rpi firmware functions

2016-10-16T08:26:12Z

The raspberrypi-firmware.h file should provide empty functions if we aren't building in that option. This makes it easier to test-build code, and not have odd warnings about unused variables if you just try to #define away the functions.

ARM: bcm2835: Add #define for VCHIQ property message.

These packets give us direct access to the firmware's power management code, as opposed to GET/SET_POWER_STATE packets that only had a couple of domains implemented. Signed-off-by: Eric Anholt Reviewed-by: Kevin Hilman

ARM: bcm2835: Add the Raspberry Pi firmware driver

This gives us a function for making mailbox property channel requests of the firmware, which is most notable in that it will let us get and set clock rates. Signed-off-by: Eric Anholt Acked-by: Stephen Warren
