2021-10-21ARM: dts: aspeed: rainier: Enable earlyconJoel Stanley1-1/+1
Rainier was missed when enabling all of the other machines in commit 239566b032f3 ("ARM: dts: aspeed: Set earlycon boot argument"). Signed-off-by: Joel Stanley <joel@jms.id.au>
2021-10-21ARM: dts: aspeed: rainier: Add front panel LEDsJoel Stanley1-0/+42
These were meant to be part of commit 4fb27b3f9176 ("ARM: dts: aspeed: rainier: Add system LEDs") but went missing. Signed-off-by: Joel Stanley <joel@jms.id.au>
2021-10-21ARM: dts: aspeed: rainier: Add 'factory-reset-toggle' as GPIOF6Isaac Kurth1-1/+1
The state of this GPIO determines whether a factory reset has been requested. If a physical switch is used, it can be high or low. During boot, the software checks and records the state of this switch. If it is different than the previous recorded state, then the read-write portions of memory are reformatted.

2021-10-21ARM: dts: aspeed: p10bmc: Use KCS 3 for MCTP bindingAndrew Jeffery2-5/+12
The MCTP LPC driver was loaded by hacking up the compatible in the devicetree node for KCS 4. With the introduction of the raw KCS driver this hack is no-longer required. Use the regular compatible string for KCS 4 and configure the appropriate SerIRQ. The reset state of the status bits on KCS 4 is inappropriate for the MCTP LPC binding. Switch to KCS 3 which has a different reset behaviour. Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>

2021-10-21ARM: dts: aspeed: everest: Add IBM Operation Panel I2C deviceEddie James1-1/+7
Set I2C bus 14 to multi-master mode and add the panel device that will register the I2C controller as a slave device. In addition, in early Everest systems, the panel device was behind an I2C switch, which doesn't work for slave mode. Get it working (albeit unreliably, since a master transaction might switch the switch at any moment) by defaulting the switch channel to the one with the panel.

Add the power-config-full-load described in: https://github.com/openbmc/docs/blob/master/designs/device-tree-gpio-naming.md#power-config-full-load The power-config-full-load gpio is designed to be used to specify how many power supplies the system should have, in rainier it is 2 or 4. If enough power supplies fail so that the system no longer has redundancy (no longer n+1), the hardware will signal to the Onboard Chip Controller that the system may be oversubscribed, and performance may need to be reduced so the system can maintain it's powered on state.

2021-09-11perf tools: Allow build-id with trailing zerosNamhyung Kim1-0/+10
Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.

2021-09-11perf tools: Fix hybrid config terms list corruptionAdrian Hunter2-9/+27
A config terms list was spliced twice, resulting in a never-ending loop when the list was traversed. Fix by using list_splice_init() and copying and freeing the lists as necessary.
