To: Wan ZongShun Cc: Linux ARM , Linus Walleij , Russell King , Linux Kernel Mailing List , Avi Fishman , Tomer Maimon , Tali Perry , Patrick Venture , Nancy Yuen , Benjamin Fair , OpenBMC Maillist Content-Type: text/plain; charset="UTF-8" Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org As the mach-netx and mach-8695 platforms are being removed now, I wonder whether we should do the same with w90x00: Here is what I found after looking at the git history and external material for it. - The supported chips (nuc910/950/960) are no longer marketed by the manufacturer - Newer chips from the same family (nuc97x, nuc980, n329x) that are still marketed have Linux BSPs but those were never submitted for upstream inclusion. - Wan ZongShun is listed as maintainer, but the last patch he wrote was in 2011. - All patches to w90x900 platform specific files afterwards are cleanups that were apparently done without access to test hardware. - The http://www.mcuos.com/ website listed in the MAINTAINERS file is no longer reachable. We do support the newer NPCM platform from Nuvoton. I don't think there are any shared drivers between the two, but I've added its maintainers to Cc anyway, in case they still (plan to) use one of those drivers. If we decide that it's time to let go, I'll would the patches below. watchdog: remove w90x900 driver spi: remove w90x900 driver ASoC: remove w90x900/nuc900 platform drivers fbdev: remove w90x900/nuc900 platform drivers Input: remove w90x900 keyboard driver Input: remove w90x900 touchscreen driver mtd: rawnand: remove w90x900 driver net: remove w90p910-ether driver rtc: remove w90x900/nuc900 driver usb: remove ehci-w90x900 driver ARM: remove w90x900 platform Documentation/watchdog/watchdog-parameters.rst | 10 - MAINTAINERS | 16 - arch/arm/Kconfig | 21 +- arch/arm/Makefile | 1 - arch/arm/configs/nuc910_defconfig | 51 - arch/arm/configs/nuc950_defconfig | 67 -- arch/arm/configs/nuc960_defconfig | 57 -- arch/arm/mach-w90x900/Kconfig | 54 -- arch/arm/mach-w90x900/Makefile | 20 - arch/arm/mach-w90x900/Makefile.boot | 4 - arch/arm/mach-w90x900/clksel.c | 88 -- arch/arm/mach-w90x900/clock.c | 121 --- arch/arm/mach-w90x900/clock.h | 40 - arch/arm/mach-w90x900/cpu.c | 238 ----- arch/arm/mach-w90x900/cpu.h | 56 -- arch/arm/mach-w90x900/dev.c | 537 ----------- arch/arm/mach-w90x900/gpio.c | 150 --- arch/arm/mach-w90x900/include/mach/entry-macro.S | 26 - arch/arm/mach-w90x900/include/mach/hardware.h | 19 - arch/arm/mach-w90x900/include/mach/irqs.h | 82 -- arch/arm/mach-w90x900/include/mach/map.h | 153 --- arch/arm/mach-w90x900/include/mach/mfp.h | 21 - arch/arm/mach-w90x900/include/mach/regs-clock.h | 49 - arch/arm/mach-w90x900/include/mach/regs-irq.h | 46 - arch/arm/mach-w90x900/include/mach/regs-ldm.h | 248 ----- arch/arm/mach-w90x900/include/mach/regs-serial.h | 54 -- arch/arm/mach-w90x900/include/mach/uncompress.h | 43 - arch/arm/mach-w90x900/irq.c | 212 ----- arch/arm/mach-w90x900/mach-nuc910evb.c | 38 - arch/arm/mach-w90x900/mach-nuc950evb.c | 42 - arch/arm/mach-w90x900/mach-nuc960evb.c | 38 - arch/arm/mach-w90x900/mfp.c | 197 ---- arch/arm/mach-w90x900/nuc910.c | 58 -- arch/arm/mach-w90x900/nuc910.h | 17 - arch/arm/mach-w90x900/nuc950.c | 52 -- arch/arm/mach-w90x900/nuc950.h | 17 - arch/arm/mach-w90x900/nuc960.c | 50 - arch/arm/mach-w90x900/nuc960.h | 17 - arch/arm/mach-w90x900/nuc9xx.h | 22 - arch/arm/mach-w90x900/regs-ebi.h | 29 - arch/arm/mach-w90x900/regs-gcr.h | 34 - arch/arm/mach-w90x900/regs-timer.h | 37 - arch/arm/mach-w90x900/regs-usb.h | 31 - arch/arm/mach-w90x900/time.c | 168 ---- drivers/input/keyboard/Kconfig | 11 - drivers/input/keyboard/Makefile | 1 - drivers/input/keyboard/w90p910_keypad.c | 264 ------ drivers/input/touchscreen/Kconfig | 9 - drivers/input/touchscreen/Makefile | 1 - drivers/input/touchscreen/w90p910_ts.c | 331 ------- drivers/mtd/nand/raw/Kconfig | 8 - drivers/mtd/nand/raw/Makefile | 1 - drivers/mtd/nand/raw/nuc900_nand.c | 304 ------ drivers/net/ethernet/Kconfig | 1 - drivers/net/ethernet/Makefile | 1 - drivers/net/ethernet/nuvoton/Kconfig | 29 - drivers/net/ethernet/nuvoton/Makefile | 6 - drivers/net/ethernet/nuvoton/w90p910_ether.c | 1082 ---------------------- drivers/rtc/Kconfig | 7 - drivers/rtc/Makefile | 1 - drivers/rtc/rtc-nuc900.c | 271 ------ drivers/spi/Kconfig | 7 - drivers/spi/Makefile | 1 - drivers/spi/spi-nuc900.c | 429 --------- drivers/usb/host/Kconfig | 6 - drivers/usb/host/Makefile | 1 - drivers/usb/host/ehci-w90x900.c | 130 --- drivers/video/fbdev/Kconfig | 14 - drivers/video/fbdev/Makefile | 1 - drivers/video/fbdev/nuc900fb.c | 760 --------------- drivers/video/fbdev/nuc900fb.h | 51 - drivers/watchdog/Kconfig | 9 - drivers/watchdog/Makefile | 1 - drivers/watchdog/nuc900_wdt.c | 303 ------ include/Kbuild | 2 - include/linux/platform_data/keypad-w90p910.h | 16 - include/linux/platform_data/spi-nuc900.h | 29 - include/linux/platform_data/video-nuc900fb.h | 79 -- sound/soc/Kconfig | 1 - sound/soc/Makefile | 1 - sound/soc/nuc900/Kconfig | 29 - sound/soc/nuc900/Makefile | 12 - sound/soc/nuc900/nuc900-ac97.c | 391 -------- sound/soc/nuc900/nuc900-audio.c | 73 -- sound/soc/nuc900/nuc900-audio.h | 108 --- sound/soc/nuc900/nuc900-pcm.c | 321 ------- 86 files changed, 1 insertion(+), 8433 deletions(-) Arnd
