Hi all, This is the fifth version of patch set. Any comments are welcome.
See the changelog below for details. The following series add initial support for the Slimport ANX7814 transmitter, a ultra-low power Full-HD (1080p60) transmitter designed for portable device. The driver was originally created and based from the work of Junhua Xia from Analogix. This driver is a refactor of the original driver and fixes different coding style lines, and different errors/warnings reported by checkpatch. Also there were things that I noticed that we need to change like: - Convert the numbered GPIO API to the new descriptor based GPIO API. - Review the DT binding - Add missing MODULE_DEVICE_TABLE(of, ...); - Fix Makefiles and Kconfig to build conditionally. - Use SIMPLE_DEV_PM_OPS() instead of the deprecated i2c .suspend and .resume callbacks. - Move to use managed device resources. - Remove dead/unused code. - And others ... Changes since v4: Rob Herring and Laurent Pinchart: - Add ports binding for describing data connections. Nicolas Boichat: - He did a big effort refactoring the driver and in order to simplify the different state machines involved and the code in general. Enric Balletbo: - Remove some magic numbers. - Use some DRM helpers. - Document better the driver in general Changes since v3: Nicolas Boichat: - Integrate sp_edid_header_result with sp_check_edid_data - Fix loop forever. - Use meaningful messages and variable names - Replace some 'while' loops and use a for loop. - Might be clearer to say >= LINK_6P75G - Convert a function to void function because always return 0 - Remove some magic numbers and refactor sp_tx_pclk_calc - Replace sp_read_reg(SP_TX_LINK_BW_SET_REG) for sp_tx_get_link_bw. - Mask bits 4:0. Bit 5 has another purpose, and 7:6 are reserved. - Use ARRAY_SIZE. - Use memset for initialization. - Simply condition if (!(c1 & POLLING_EN) || (c & POLLING_ERR)) - Don not use a temporal variable write the value directly. - Fix various typos - Return directly PTR_ERR. Dan Carpenter: - Refactor while loop removing the earlier condition and do while (--c) instead - Simplify double negative and fix alignment - Remove the superflous casts to u16 and parens - Remove debug printks and use ftrace instead. - Flip this condition around and pull the code in one indent level. - Fix return value 'ret' that should be an int. It causes a signedness bug later. - Use better style for devm_kzalloc - Get rid of AUX_*. They aren't used much and we could easily use normal error codes instead. Enric Balletbo - Fix errors reported by scripts/checkpatch.pl --strict --subjective - Remove XTAL_CLK_M10 XTAL_CLK definitions - replace ulong for unsigned long - remove some magic numbers and refactor sp_tx_enable_audio_output - remove some magic numbers and refactor sp_tx_phy_auto_test Changes since v2 (requested by Daniel Kurtz): - clean up the typos, and little nits requested by Dan. - move to the drm/bridge directory - rename the files, variables, types, etc. to anx78xx - plumb through the context struct to all functions that act on the device - use proper messaging (dev_ rather than pr_, _dbg/_err rather than _info) Changes since v1: - As requested by Greg, move from staging to a subsystem.
