misc: eeprom: at24: register nvmem only after eeprom is ready to use

2020-09-17T11:55:41Z

commit 45df80d7605c25055a85fbc5a8446c81c6c0ca24 upstream. During nvmem_register() the nvmem core sends notifications when: - cell added - nvmem added and during these notifications some callback func may access the nvmem device, which will fail in case of at24 eeprom because regulator and pm are enabled after nvmem_register().

misc: eeprom: at24: fix regulator underflow

2020-03-12T08:02:34Z

The at24 driver attempts to read a byte from the device to validate that it's actually present, and if not, disables the vcc regulator and returns -ENODEV. However, between the read and the error handling path, pm_runtime_idle() is called and invokes the driver's suspend callback, which also disables the vcc regulator. This leads to an underflow of the regulator enable count if the EEPROM is not present. Move the pm_runtime_suspend() call to be after the error handling path to resolve this.

misc: eeprom: at24: support pm_runtime control

2020-01-23T11:52:57Z

Although in the most platforms, the power of eeprom are alway on, some platforms disable the eeprom power in order to meet low power request. This patch add the pm_runtime ops to control power to support all platforms. Signed-off-by: Bibby Hsieh [Bartosz: rebased on top of current at24/for-next] Signed-off-by: Bartosz Golaszewski

eeprom: at24: remove the write-protect pin support

2020-01-09T09:51:13Z

NVMEM framework is an interface for the at24 EEPROMs as well as for other drivers, instead of passing the wp-gpios over the different drivers each time, it would be better to pass it over the NVMEM subsystem once and for all. Removing the support for the write-protect pin after adding it to the NVMEM subsystem. Signed-off-by: Khouloud Touil Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

Pull i2c updates from Wolfram Sang: "I2C has mostly driver updates this time. The few noteworthy changes are: the core has now support for analog and digital filters with at91 being the first user, a core addition to replace the NULL returning i2c_new_probed_device() with an ERR_PTR variant, and the pxa driver has finally being moved to use the generic I2C slave interface. We have quite a significant number of reviews per patch this time, so thank you to all involved!" * 'i2c/for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (37 commits) video: fbdev: matrox: convert to i2c_new_scanned_device i2c: icy: convert to i2c_new_scanned_device i2c: replace i2c_new_probed_device with an ERR_PTR variant i2c: Fix Kconfig indentation i2c: smbus: Don't filter out duplicate alerts i2c: i801: Correct Intel Jasper Lake SOC naming i2c: i2c-stm32f7: fix 10-bits check in slave free id search loop i2c: iproc: Add i2c repeated start capability i2c: remove helpers for ref-counting clients i2c: tegra: Use dma_request_chan() directly for channel request i2c: sh_mobile: Use dma_request_chan() directly for channel request i2c: qup: Use dma_request_chan() directly for channel request i2c: at91: Use dma_request_chan() directly for channel request i2c: rcar: Remove superfluous call to clk_get_rate() i2c: pxa: remove unused i2c-slave APIs i2c: pxa: migrate to new i2c_slave APIs i2c: cros-ec-tunnel: Make the device acpi compatible i2c: stm32f7: report dma error during probe i2c: icy: no need to populate address for scanned device i2c: xiic: Fix kerneldoc warnings ...
