From 9a8da6082ddb4689baf34dcdf2a53985e25753f3 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 11 Mar 2020 09:31:31 +0100 Subject: tty: serial: ifx6x60: Convert to GPIO descriptors This driver for the Intel MID never seems to have been properly integrated upstream: the platform data in is not used anywhere in the kernel and haven't been since it was merged into the kernel in 2010. There might be out-of-tree users, so I don't want to delete the driver, but I will refactor it to use GPIO descriptors, which means that out-of-tree users will need to adapt. There are several examples in the kernel of how to provide the resources necessary for using GPIO descriptors to pass in the GPIO lines, for the MID platform in particular, it will suffice to inspect the code in files like: arch/x86/platform/intel-mid/device_libs/platform_bt.c This refactoring transfers all GPIOs in the driver, including a hard-coded "PMU reset" in the driver to use GPIO descriptors instead. The following named GPIO descriptors need to be supplied: - reset - power - mrdy - srdy - rst_out - pmu_reset Cc: Russ Gorby Signed-off-by: Linus Walleij Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20200311083131.693908-2-linus.walleij@linaro.org Signed-off-by: Greg Kroah-Hartman --- include/linux/spi/ifx_modem.h | 5 ----- 1 file changed, 5 deletions(-) (limited to 'include/linux/spi') diff --git a/include/linux/spi/ifx_modem.h b/include/linux/spi/ifx_modem.h index 694268c78d5d..6d19b09139d0 100644 --- a/include/linux/spi/ifx_modem.h +++ b/include/linux/spi/ifx_modem.h @@ -3,12 +3,7 @@ #define LINUX_IFX_MODEM_H struct ifx_modem_platform_data { - unsigned short rst_out; /* modem reset out */ - unsigned short pwr_on; /* power on */ - unsigned short rst_pmu; /* reset modem */ unsigned short tx_pwr; /* modem power threshold */ - unsigned short srdy; /* SRDY */ - unsigned short mrdy; /* MRDY */ unsigned char modem_type; /* Modem type */ unsigned long max_hz; /* max SPI frequency */ unsigned short use_dma:1; /* spi protocol driver supplies -- cgit v1.2.3
