Signed-off-by: Ksenija Stanojevic --- Changes in v7: - remove touch_ret variable in probe and use ret instead - make error check on of_property_read_u32 in probe Changes in v6: - update copyright Changes in v5: - add field void __iomem *base to struct mxs_lradc_adc - change arguments in all functions for accessing I/O memory to follow the previous change. - use devm_ioremap for mapping I/O memory Changes in v4: - update copyright - use platform_get_irq_byname - use irq_of_parse_and_map Changes in v3: - make buffer large enough for timestamps - remove unnecessary blank lines Changes in v2: - improve commit message - do not change spacing in Kconfig - impove formating - remove wrapper show_scale_avail - use correct syntax for comments - use devm_iio_trigger_alloc - do not allocate buffer dynamically - use iio_device_claim_*_mode helpers - add spinlock in struct mxs_lradc_ts to enable locking in interrupt handler - only grab irqs that are relevant to adc - remove blank line at the end of the file - change licence to GPL - add copyright drivers/input/touchscreen/Kconfig | 10 ++++++++++ drivers/input/touchscreen/Makefile | 1 + 2 files changed, 11 insertions(+) diff --git a/drivers/input/touchscreen/Kconfig b/drivers/input/touchscreen/Kconfig index 2fb1f43..49ea962 100644 --- a/drivers/input/touchscreen/Kconfig +++ b/drivers/input/touchscreen/Kconfig @@ -305,6 +305,16 @@ config TOUCHSCREEN_EGALAX_SERIAL To compile this driver as a module, choose M here: the module will be called egalax_ts_serial. +config TOUCHSCREEN_MXS_LRADC + tristate "Freescale i.MX23/i.MX28 LRADC touchscreen" + depends on MFD_MXS_LRADC + help + Say Y here if you have a touchscreen connected to the low-resolution + analog-to-digital converter (LRADC) on an i.MX23 or i.MX28 processor. + + To compile this driver as a module, choose M here: the module will be + called mxs-lradc-ts. + config TOUCHSCREEN_FT6236 tristate "FT6236 I2C touchscreen" depends on I2C diff --git a/drivers/input/touchscreen/Makefile b/drivers/input/touchscreen/Makefile index b4373d6..9f2b76b 100644 --- a/drivers/input/touchscreen/Makefile +++ b/drivers/input/touchscreen/Makefile @@ -54,6 +54,7 @@ obj-$(CONFIG_TOUCHSCREEN_MIGOR) += migor_ts.o obj-$(CONFIG_TOUCHSCREEN_MMS114) += mms114.o obj-$(CONFIG_TOUCHSCREEN_MTOUCH) += mtouch.o obj-$(CONFIG_TOUCHSCREEN_MK712) += mk712.o +obj-$(CONFIG_TOUCHSCREEN_MXS_LRADC) += mxs-lradc-ts.o obj-$(CONFIG_TOUCHSCREEN_HP600) += hp680_ts_input.o obj-$(CONFIG_TOUCHSCREEN_HP7XX) += jornada720_ts.o obj-$(CONFIG_TOUCHSCREEN_IPAQ_MICRO) += ipaq-micro-ts.o -- 1.9.1
