2020-07-13ARM: dts: ls1021a: output PPS signal on FIPER2Yangbo Lu1-1/+1
The timer fixed interval period pulse generator register is used to generate periodic pulses. The down count register loads the value programmed in the fixed period interval (FIPER). At every tick of the timer accumulator overflow, the counter decrements by the value of TMR_CTRL[TCLK_PERIOD]. It generates a pulse when the down counter value reaches zero. It reloads the down counter in the cycle following a pulse. To use the TMR_FIPER register to generate desired periodic pulses. The value should programmed is, desired_period - tclk_period Current tmr-fiper2 value is to generate 100us periodic pulses. (But the value should have been 99995, not 99990. The tclk_period is 5.) This patch is to generate 1 second periodic pulses with value 999999995 programmed which is more desired by user.

Some Makefiles already pass -fno-stack-protector unconditionally. For example, arch/arm64/kernel/vdso/Makefile, arch/x86/xen/Makefile. No problem report so far about hard-coding this option.

2020-07-06ARM: dts sunxi: Relax a bit the CMA pool allocation rangeMaxime Ripard3-3/+3
The hardware codec on the A10, A10s, A13 and A20 needs buffer in the first 256MB of RAM. This was solved by setting the CMA pool at a fixed address in that range. However, in recent kernels there's something else that comes in and reserve some range that end up conflicting with our default pool requirement, and thus makes its reservation fail. The video codec will then use buffers from the usual default pool, outside of the range it can access, and will fail to decode anything. Since we're only concerned about that 256MB, we can however relax the allocation to just specify the range that's allowed, and not try to enforce a specific address.

Instead, expose the key via the input framework, as SW_MACHINE_COVER The chip-detect GPIO is actually detecting if the cover is closed. Technically it's possible to use the SD card with open cover. The only downside is risk of battery falling out and user being able to physically remove the card. The behaviour of SD card not being available when the device is open is unexpected and creates more problems than it solves. There is a high chance, that more people accidentally break their rootfs by opening the case without physically removing the card.

2020-06-29ARM: dts: am335x-pocketbeagle: add gpio-line-namesDrew Fustini1-0/+144
The BeagleBoard.org PocketBeagle has P1 and P2 headers [0] which expose many of the TI AM3358 SoC balls to stacking expansion boards called "capes", or to other external connections like jumper wires connected to a breadboard. Note: the AM3358 die is actually embedded inside of the OSD335x-SM System-in-Package (SiP) [1] but that is irrelevant to the gpio driver. Many of the P1 and P2 header pins can muxed to a GPIO line. The gpio-line-names describe which P1 or P2 pin that line goes to and the default mux for that P1 or P2 pin if it is not GPIO. Some GPIO lines are named "[NC]" as the corresponding balls are not routed to anything on the PCB. The goal for these names is to make it easier for a user viewing the output of gpioinfo to determine which P1 or P2 pin is connected to a GPIO line. The output of gpioinfo on a PocketBeagle would be: gpiochip0 - 32 lines: line 0: "[NC]" unused input active-high line 1: "[NC]" unused input active-high line 2: "P1.08 [SPI0_CLK]" unused input active-high line 3: "P1.10 [SPI0_MISO]" unused input active-high line 4: "P1.12 [SPI0_MOSI]" unused input active-high line 5: "P1.06 [SPI0_CS]" unused input active-high line 6: "[MMC0_CD]" "cd" input active-low [used] line 7: "P2.29 [SPI1_CLK]" unused input active-high line 8: "[SYSBOOT]" unused input active-high line 9: "[SYSBOOT]" unused input active-high line 10: "[SYSBOOT]" unused input active-high line 11: "[SYSBOOT]" unused input active-high line 12: "P1.26 [I2C2_SDA]" unused input active-high line 13: "P1.28 [I2C2_SCL]" unused input active-high line 14: "P2.11 [I2C1_SDA]" unused input active-high line 15: "P2.09 [I2C1_SCL]" unused input active-high line 16: "[NC]" unused input active-high line 17: "[NC]" unused input active-high line 18: "[NC]" unused input active-high line 19: "P2.31 [SPI1_CS]" unused input active-high line 20: "P1.20 [PRU0.16]" unused input active-high line 21: "[NC]" unused input active-high line 22: "[NC]" unused input active-high line 23: "P2.03" unused input active-high line 24: "[NC]" unused input active-high line 25: "[NC]" unused input active-high line 26: "P1.34" unused input active-high line 27: "P2.19" unused input active-high line 28: "[NC]" unused input active-high line 29: "[NC]" unused input active-high line 30: "P2.05 [UART4_RX]" unused input active-high line 31: "P2.07 [UART4_TX]" unused input active-high gpiochip1 -

The BeagleBone Black has P8 and P9 headers [0] which expose many of the AM3358 ZCZ SoC balls to stacking expansion boards called "capes", or to other external connections like jumper wires connected to a breadboard. BeagleBone users will often refer to the "Cape Exanpsion Headers" pin diagram [1] as it is in the "Bone101" getting started tutorial. [2] Most of the P8 and P9 header pins can muxed to a GPIO line. The gpio-line-names describe which P8 or P9 pin that line goes to and the default mux for that P8 or P9 pin if it is not GPIO. For example, gpiochip 1 line 0 is connected to P8 header pin 25 (P8_25) however the default device tree has the corresponding BGA ball (ZCZ U7) muxed to mmc1_dat0 as it is used for the on-board eMMC chip. For that GPIO line to be used, one would need to modify the device tree to disable the eMMC and change the pin mux for that ball to GPIO mode. Some of the AM3358 ZCZ balls corresponding to GPIO lines are not routed to a P8 or P9 header, but are instead wired to some peripheral device like on-board eMMC, HDMI framer IC, or status LEDs. Those names are in brackets to denote those GPIO lines can not be used. Some GPIO lines are named "[NC]" as the corresponding balls are not routed to anything on the PCB. The goal for these names is to make it easier for a user viewing the output of gpioinfo to determine which P8 or P9 pin is connected to a GPIO line. The output of gpioinfo on a BeagleBone Black would be: gpiochip0 - 32 lines: line 0: "[ethernet]" unused input active-high line 1: "[ethernet]" unused input active-high line 2: "P9_22 [spi0_sclk]" unused input active-high line 3: "P9_21 [spi0_d0]" unused input active-high line 4: "P9_18 [spi0_d1]" unused input active-high line 5: "P9_17 [spi0_cs0]" unused input active-high line 6: "[sd card]" "cd" input active-low [used] line 7: "P9_42A [ecappwm0]" unused input active-high line 8: "P8_35 [hdmi]" unused input active-high line 9: "P8_33 [hdmi]" unused input active-high line 10: "P8_31 [hdmi]" unused input active-high line 11: "P8_32 [hdmi]" unused input active-high line 12: "P9_20 [i2c2_sda]" unused input active-high line 13: "P9_19 [i2c2_scl]" unused input active-high line 14: "P9_26 [uart1_rxd]" unused input active-high line 15: "P9_24 [uart1_txd]" unused input active-high line 16: "[ethernet]" unused input active-high line 17: "[ethernet]" unused input active-high line 18: "[usb]" unused input active-high line 19: "[hdmi]" unused input active-high line 20: "P9_41B" unused input active-high line 21: "[ethernet]" unused input active-high line 22: "P8_19 [ehrpwm2a]" unused input active-high line 23: "P8_13 [ehrpwm2b]" unused input active-high line 24: "[NC]" unused input active-high line 25: "[NC]" unused input active-high line 26: "P8_14" unused input active-high line 27: "P8_17" unused input active-high line 28: "[ethernet]" unused input active-high line 29: "[ethernet]" unused input active-high line 30: "P9_11 [uart4_rxd]" unused input active-high line 31: "P9_13 [uart4_txd]" unused input active-high gpiochip1 -
