It may make sense to split the Microsoft Surface hardware platform drivers out to a separate subdirectory, since some of it may be shared between ARM and x86 in the future (regarding devices like the Surface Pro X). Further, newer Surface devices will require additional platform drivers for fundamental support (mostly regarding their embedded controller), which may also warrant this split from a size perspective. This commit introduces a new platform/surface subdirectory for the Surface device family, with subsequent commits moving existing Surface drivers over from platform/x86. A new MAINTAINERS entry is added for this directory. Patches to files in this directory will be taken up by the platform-drivers-x86 team (i.e. Hans de Goede and Mark Gross) after they have been reviewed by Maximilian Luz. Signed-off-by: Maximilian Luz <luzmaximilian@xxxxxxxxx> --- Changes in v2: - Do not create a separate MAINTAINERS entry for platform/surface. Instead add drivers/platform/surface to x86 platform drivers entry. This incorporates recent changes in the x86 platform driver MAINTAINERS entry. - Fix typo in commit message. Changes in v3: - Add separate MAINTAINERS entry for platform/surface - Add Maximilian Luz as reviewer for platform/surface Changes in v4: - Rename MAINTAINERS entry to be similar to platform/chrome. - Rename Kconfig options to be similar to platform/chrome (PLATFORM -> PLATFORMS) - Drop placeholder comments. --- MAINTAINERS | 9 +++++++++ drivers/platform/Kconfig | 2 ++ drivers/platform/Makefile | 1 + drivers/platform/surface/Kconfig | 14 ++++++++++++++ drivers/platform/surface/Makefile | 5 +++++ 5 files changed, 31 insertions(+) create mode 100644 drivers/platform/surface/Kconfig create mode 100644 drivers/platform/surface/Makefile diff --git a/MAINTAINERS b/MAINTAINERS index 2a2170ff3a91..9fea3ce2db2d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -11532,6 +11532,15 @@ F: drivers/scsi/smartpqi/smartpqi*.[ch] F: include/linux/cciss*.h F: include/uapi/linux/cciss*.h +MICROSOFT SURFACE HARDWARE PLATFORM SUPPORT +M: Hans de Goede <hdegoede@xxxxxxxxxx> +M: Mark Gross <mgross@xxxxxxxxxxxxxxx> +M: Maximilian Luz <luzmaximilian@xxxxxxxxx> +L: platform-driver-x86@xxxxxxxxxxxxxxx +S: Maintained +T: git git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git +F: drivers/platform/surface/ + MICROSOFT SURFACE PRO 3 BUTTON DRIVER M: Chen Yu <yu.c.chen@xxxxxxxxx> L: platform-driver-x86@xxxxxxxxxxxxxxx diff --git a/drivers/platform/Kconfig b/drivers/platform/Kconfig index 971426bb4302..18fc6a08569e 100644 --- a/drivers/platform/Kconfig +++ b/drivers/platform/Kconfig @@ -13,3 +13,5 @@ source "drivers/platform/chrome/Kconfig" source "drivers/platform/mellanox/Kconfig" source "drivers/platform/olpc/Kconfig" + +source "drivers/platform/surface/Kconfig" diff --git a/drivers/platform/Makefile b/drivers/platform/Makefile index 6fda58c021ca..4de08ef4ec9d 100644 --- a/drivers/platform/Makefile +++ b/drivers/platform/Makefile @@ -9,3 +9,4 @@ obj-$(CONFIG_MIPS) += mips/ obj-$(CONFIG_OLPC_EC) += olpc/ obj-$(CONFIG_GOLDFISH) += goldfish/ obj-$(CONFIG_CHROME_PLATFORMS) += chrome/ +obj-$(CONFIG_SURFACE_PLATFORMS) += surface/ diff --git a/drivers/platform/surface/Kconfig b/drivers/platform/surface/Kconfig new file mode 100644 index 000000000000..b67926ece95f --- /dev/null +++ b/drivers/platform/surface/Kconfig @@ -0,0 +1,14 @@ +# SPDX-License-Identifier: GPL-2.0-only +# +# Microsoft Surface Platform-Specific Drivers +# + +menuconfig SURFACE_PLATFORMS + bool "Microsoft Surface Platform-Specific Device Drivers" + default y + help + Say Y here to get to see options for platform-specific device drivers + for Microsoft Surface devices.
