Subject: [V2, 0/2] media: i2c: add support for DW9768 VCM driver
Date: Thu, 5 Sep 2019 15:21:40 +0800	[thread overview]
Message-ID: <20190905072142.14606-1-dongchun.zhu@mediatek.com> (raw)

From: Dongchun Zhu <dongchun.zhu-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

Hello,

Add a v4l2 sub-device driver for Dongwoon's DW9768 lens voice coil.
This is a voice coil module using the i2c bus to control the focus position.

The DW9768 can control the position with 10 bits value and
consists of two 8 bit registers show as below.
register 0x04(DW9768_REG_POSITION):
     +---+---+---+---+---+---+---+---+
     |D07|D06|D05|D04|D03|D02|D01|D00|
     +---+---+---+---+---+---+---+---+
register 0x03:
     +---+---+---+---+---+---+---+---+
     |---|---|---|---|---|---|D09|D08|
     +---+---+---+---+---+---+---+---+

This driver supports:
 - set DW9768 to standby mode once suspend and turn it back to active if resume
 - set the position via V4L2_CID_FOCUS_ABSOLUTE ctrl

Mainly changes of v2 are addressing the comments from Tomasz, Bingbu, Andy,
including,
 - Use i2c_smbus_write_byte_data/i2c_smbus_write_block_data to write I2C register
 - Adopt the runtime PM suspend/resume callbacks to powering off/on
 - Check the PM runtime status before powering off in dw9768_remove function
 - Add one more regulator vin for the I2C interface
 - Remove or refine redundant log print
 - Fix other reviewed issues in v1
