Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

Description: Make it possible to switch the PicoLCD device between LCD
|
|
(firmware) and bootloader (flasher) operation modes.
|
|
|
|
Reading: returns list of available modes, the active mode being
|
|
enclosed in brackets ('[' and ']')
|
|
|
|
Writing: causes operation mode switch. Permitted values are
|
|
the non-active mode names listed when read.
|
|
|
|
Note: when switching mode the current PicoLCD HID device gets
|
|
disconnected and reconnects after above delay (see attribute
|
|
operation_mode_delay for its value).

Description: Make it possible to adjust defio refresh rate.
|
|
|
|
Reading: returns list of available refresh rates (expressed in Hz),
|
|
the active refresh rate being enclosed in brackets ('[' and ']')
|
|
|
|
Writing: accepts new refresh rate expressed in integer Hz
|
|
within permitted rates.
|
|
|
|
Note: As device can barely do 2 complete refreshes a second
|
|
it only makes sense to adjust this value if only one or two
|
|
tiles get changed and it's not appropriate to expect the application
|
|
to flush its tiny changes explicitly at higher than default rate.
