tpm: Don't cleanup unless an error happens

2020-04-16T06:36:28Z

At present the cleanup() method is called on every transfer. It should only be called on failing transfers. Fix this and tidy up the error handling a little. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

tpm: cr50: Use the correct GPIO binding

2020-04-16T06:36:28Z

This device should use ready-gpios rather than ready-gpio. Fix it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

tpm: cr50: Release locality on exit

2020-04-16T06:36:28Z

At present the cr50 driver claims the locality and does not release it for Linux. This causes problems. Fix this by tracking what is claimed, and adding a 'remove' method. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

tpm: Add a driver for H1/Cr50

2020-02-07T14:46:35Z

H1 is a Google security chip present in recent Chromebooks, Pixel phones and other devices. Cr50 is the name of the software that runs on H1 in Chromebooks. This chip is used to handle TPM-like functionality and also has quite a few additional features. Add a driver for this. Signed-off-by: Simon Glass

dm: gpio: Allow control of GPIO uclass in SPL

2019-12-15T00:52:29Z

At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass is included in SPL/TPL without any control for boards. Some boards may want to disable this to reduce code size where GPIOs are not needed in SPL or TPL. Add a new Kconfig option to permit this. Default it to 'y' so that existing boards work correctly. Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to preserve the current behaviour. Also update the 74x164 GPIO driver since it cannot build with SPL. This allows us to remove the hacks in config_uncmd_spl.h and Makefile.uncmd_spl (eventually those files should be removed). Signed-off-by: Simon Glass Reviewed-by: Bin Meng

common: Drop linux/crc8.h

We have an existing U-Boot header for the one function that this defines. Use that instead of the linux/ one. Move over the nice comment. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

tpm2: Don't assume active low reset value

2019-10-15T14:40:02Z

The reset function sets the pin to 0 then 1 but if the pin is marked ACTIVE_LOW in the DT it gets inverted and leaves the TPM in reset. Let the gpio driver take care of the reset polarity. Signed-off-by: Kayla Theil
