changes since v3: - update Kconfig as well - drop chip names from comment in driver header - add manufacturer check for Fintek again, Nuvoton not possible - drop revision printing for Nuvoton - restructure defines again - add new model 427G changes since v2: (p1 only) - rename macros that change behavior - use chip type not device id in the macros - reorder defines a bit changes since v1: - remove unused define - fix bug where (base + 2) was used as second data bit - add macros for "inverted" and "single data bit" This series first enables a SuperIO GPIO driver to support a chip from the vendor Nuvoton, the driver is for Fintek devices but those just are very similar. And in watchdog and hwmon subsystems these SuperIO drivers also share code and are sometimes called a family. In another step the individual banks receive a label to tell them apart, a step which potentially changes an interface to legacy users that might rely on all banks having the same label, or an exact label. But since a later patch wants to use GPIO_LOOKUP unique labels are needed and i decided to assign them for all supported chips. In a following patch the Simatic GPIO LED driver is extended to provide LEDs in case that SuperIO GPIO driver can be loaded. Last but not least the watchdog module of that same SuperIO gets loaded on a best effort basis. Note similar patches have appreared before as "[PATCH v3 0/1] add device driver for Nuvoton SIO gpio function" The main difference here is that i added chip support to an existing driver instead of creating a new one. And that i actually propose all patches and do not just have the LED patch for Simatic as an example. Also note that the patches are based on "[PATCH v6 00/12] platform/x86: introduce p2sb_bar() helper" Henning Schild (5): gpio-f7188x: Add GPIO support for Nuvoton NCT6116 gpio-f7188x: use unique labels for banks/chips leds: simatic-ipc-leds-gpio: add new model 227G platform/x86: simatic-ipc: enable watchdog for 227G platform/x86: simatic-ipc: add new model 427G drivers/gpio/Kconfig | 3 +- drivers/gpio/gpio-f7188x.c | 229 +++++++++++------- drivers/leds/simple/simatic-ipc-leds-gpio.c | 42 +++- drivers/platform/x86/simatic-ipc.c | 10 +- .../platform_data/x86/simatic-ipc-base.h | 1 + include/linux/platform_data/x86/simatic-ipc.h | 2 + 6 files changed, 194 insertions(+), 93 deletions(-) -- 2.35.1
