Subject: [PATCHv6 00/11] Introduce RK806 Support
Hi,
The Rockchip RK3588 Evaluation Boards as well as the Rock 5
boards and probably most other RK3588 boards use SPI connected
RK806 PMICs. Downstream this is handled by a new driver, but
apart from being SPI connected this chip is quite similar to
the other Rockchip PMICs (and RK806 is promoted to also support
I2C). Thus this series instead updates the RK808 driver(s).
Changelog since PATCHv5:
* https://lore.kernel.org/all/20230109172723.60304-1-sebastian.reichel@collabora.com/
* add Reviewed-by from Rob Herring to the rk806 DT binding patch
* drop useless wrapper functions for rk8xx_i2c_suspend and rk8xx_i2c_resume
* put .num_resources after .resources for rk806_pwrkey_resources
* simplify dual_support logic by storing IRQF_SHARED or 0 instead of bool
* add missing spaces around + and - in rk806
* add new patch using device_get_match_data() in rk8xx-i2c and removing
the pointless dev_info printing the chip version
* call devm_mfd_add_devices() with id=0 and rely on mfd_cell to have the .id
field configured to either PLATFORM_DEVID_AUTO or PLATFORM_DEVID_NONE
* add check if more than 128 bytes are tried to be received/sent, which would
overflow the command register
* add RK806_CMD_WITH_SIZE() define
Changelog since PATCHv4:
* https://lore.kernel.org/all/20221020204251.108565-1-sebastian.reichel@collabora.com/
* rebase to v6.2-rc1
- dropped 'regulator: rk808: reduce 'struct rk808' usage' (queued to 6.2-rc1)
- dropped 'regulator: rk808: Use dev_err_probe' (queued to 6.2-rc1)
- dropped 'rtc: rk808: reduce 'struct rk808' usage' (queued to 6.2-rc1)
* use 'MFD_RK8XX' for the MFD driver supporting all the MFD8XX chips
* added author tags to drivers/mfd/rk8xx-core.c. They were missing because
I moved the original header over to the i2c specific file and wrote the
new header from scratch. I suppose it's better to have the author tags
in both files.
* fix Rob's comments for the rk806 YAML binding
* add defines for rk806 command indexes
* modify rk806 code, so that it is capable of mult-write
Changelog since PATCHv3:
* https://lore.kernel.org/all/20220909175522.179175-1-sebastian.reichel@collabora.com/
* Dropped removing REGMAP_I2C dependency from RK817 ASoC driver (applied)
* Rename MFD_RK808 to MFD_RK8XX to be consistent. It makes sense to do this now,
since the patchset touches all the child drivers anyways.
* rebase to v6.1-rc1
* collected a couple of Acks
* update rk806 DT binding according to DT maintainer feedback
* add missing pinmux config to the rk806 DT binding
* update rk806_spi_bus_write and rk806_spi_bus_read
* replaced some constants with sizeof or defines
* used capitalized comments
* rename regmap_find_closest_bigger to regulator_find_closest_bigger, not sure
why I prefixed it with regmap_ in the first place
* use rk8xx_is_enabled_wmsk_regmap instead of regulator_is_enabled_regmap for
the switching regulators to correctly report the state
* reordered the first few patches grouping the MFD patches together
Changelog since PATCHv2:
* https://lore.kernel.org/all/20220908003107.220143-1-sebastian.reichel@collabora.com/
* Change DT binding to not allow nldo-reg6
* Fix DT binding to check for [np]ldo-reg instead of [np]ldo_reg
* remove rk806_get_voltage_sel_regmap in favour of regulator_get_voltage_sel_regmap
* drop rk806_set_voltage in favour of regulator_set_voltage_sel_regmap
* use regulator_set_ramp_delay_regmap
* drop possibly incorrect printing of chip id register address in case of errors
Changelog since PATCHv1:
* https://lore.kernel.org/all/20220831215437.117880-1-sebastian.reichel@collabora.com/
* Collect Acked-by
* Avoid if/else checks for regulator id in rk806 regulator driver
* Fix indentation in DTS example section of the rk806 binding
* Use absolute path for regulator.yaml referencing in the rk806 binding
* Reduce pattern for DCDC regulators to only allow 1-10
* replace uppercase name with lowercase ones in regulator names
* replace _ with - in regulator names
