Changes in v8: - Addressed review comments from Uwe - Replace pwm_get_state with pwm_init_state - Use pwm_set_relative_duty_cycle instead of manually setting period and duty cycle Changes in v7: - Add Reviewed-by tag back to dt-binding patch Changes in v6: - Rebase off latest drm-misc-next - Replace pwm_apply_state with pwm_apply_might_sleep Changes in v5: - Address minor style issues in sharp-memory.c Changes in v4: - Remove redundant dev_err Changes in v3: - Fix file path in MAINTAINERS file - Address review comments - Simplify mode selection based on match data instead of model Changes in v2: - Credited Mehdi Djait in commit messages - Renamed sharp,sharp-memory.yaml to sharp,ls010b7dh04.yaml - Using strings instead of int for vcom-mode in dt-binding - Fixed indentation of binding example - Removed binding header - Removed extra whitespace in sharp-memory.c - Fixed error handling in sharp-memory.c - Added match data to of_device_id table to be in-sync with spi_device_id table - Replaced redundant function with spi_get_device_match_data - Sorted header files in sharp-memory.c --- Alex Lanzano (2): dt-bindings: display: Add Sharp Memory LCD bindings drm/tiny: Add driver for Sharp Memory LCD .../bindings/display/sharp,ls010b7dh04.yaml | 92 +++ MAINTAINERS | 6 + drivers/gpu/drm/tiny/Kconfig | 20 + drivers/gpu/drm/tiny/Makefile | 1 + drivers/gpu/drm/tiny/sharp-memory.c | 666 ++++++++++++++++++ 5 files changed, 785 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/sharp,ls010b7dh04.yaml create mode 100644 drivers/gpu/drm/tiny/sharp-memory.c
