This repo is a fork of m-weigand's custom linux kernel for the pinenote intended for testing tweaks and added features. Novel branches so far:

• tunable_2bit_thresholds -- clone of branch_pinenote_6-3-10_v1 with modifications to allow changing thresholds for 4 tone grayscale mode (bw_mode = 3) via module parameters.

Description of new branches and merge order

Branches

• (pinenote_6-2_v3)[https://github.com/m-weigand/linux/tree/pinenote_6-2_v3] -- Kernel 6.2 with patches applied to work on the Pinenote. See section below for a list of merged branches

• mw/rk35/pinenote-next-t1 -- Contains all changes merged into one branch that can be used on the Pinenote.

• mw/rk35/ebc-drm-v5-modifications-t1 -- Changes to the rockchip_ebc driver controlling the Pinenote epd display

• mw/rk35/pinenote-defconfig-changes -- Changes to the Pinenote defconfig tree

• mw/rk35/pinenote_dts_changes -- Changes to the Pinenote device tree

• mw/rk35/rk356x-rga -- Changes to the RGA V4L2 driver for the rockchip-rga of the Pinenote. The RGA can be used to convert RGB images to Y4 grayscale for the EPD display. It also supports dithering to monochrome colors.

• mw/rk35/tps65185 -- some fixes/additions to the tps65185 epd pmic driver, mostly related to resume/suspend
