pci: Drop DM_PCI

This option has not effect now. Drop it, using PCI instead where needed. Signed-off-by: Simon Glass

gpio: Add a GPIO config

2021-09-04T16:26:02+00:00

At present we have SPL_GPIO and TPL_GPIO but not piain GPIO. This works because there is a special build rule in Makefile that always includes the drivers/gpio directory. It is better to have all driver directories included by drivers/Makefile and there is already a rule in there for this purpose. It just needs a Kconfig for U-Boot proper, so add one. Enable the option always for now, since this mimics current behaviour. This can be updated once DM_GPIO is used everywhere. Signed-off-by: Simon Glass

Kconfig: Remove all default n/no options

default n/no doesn't need to be specified. It is default option anyway. Signed-off-by: Michal Simek [trini: Rework FSP_USE_UPD portion] Signed-off-by: Tom Rini

gpio: mcp230xx: Introduce new driver

2021-08-22T08:53:14+00:00

Introduce driver for I2C based MCP230xx GPIO chips, which are quite common and already well supported by the Linux kernel. Reviewed-by: Simon Glass Signed-off-by: Sebastian Reichel Reviewed-by: Simon Glass

Rename GPIO_SUPPORT to GPIO

Rename these options so that CONFIG_IS_ENABLED can be used with them. Signed-off-by: Simon Glass

gpio: Add driver for Nomadik GPIO

2021-07-14T20:47:56+00:00

Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson Ux500 SoCs (and some older Nomadik SoCs). It uses registers where each GPIO is represented as a single bit, plus "set" and "clear" registers that allow updating the state without having to read the existing state. The driver implements support for it for use together with DM_GPIO and the existing ste-dbx5x0.dtsi device tree. Cc: Linus Walleij Signed-off-by: Stephan Gerhold Reviewed-by: Linus Walleij

gpio: pca953x: Add missing i2c dependency

pca953x also depends on i2c that's why add dependency to Kconfig. Where GPIO is enabled but I2C compilation error pops up. Signed-off-by: Michal Simek Reviewed-by: Heiko Schocher

gpio: Add support for DM GPIO for Kirkwood

2021-01-27T06:25:39+00:00

The Armada driver also works on Nedap's custom Kirkwood board with a Marvell 88F6180 CPU. The original commit of that driver, commit 704d9a645e17 ("gpio: Add DM GPIO driver for Marvell MVEBU"), also mentions that this driver would be suitable for Kirkwood. This does not completely replace the Kirkwood specific driver as there are still boards depending on that driver. Signed-off-by: Harm Berntsen CC: Stefan Roese , Reviewed-by: Stefan Roese
