Hello, due to this commit (ARM: OMAP2+: Disable code that currently does not work with multiplaform) https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/media/rc/Kconfig?id=a62a6e98c370ccca37d353a5f763b532411a4c14 lirc driver for Nokia N900 (ir-rx51) cannot be enabled via make menuconfig. It is because Nokia N900 support cannot be compiled without ARCH_MULTIPLATFORM, but Nokia N900 lirc driver (IR_RX51) cannot be compiled when ARCH_MULTIPLATFORM is enabled. Because ir-rx51 driver is just for Nokia N900 it is nonsense to have such condition because nobody can use ir-rx51 driver... It is even not possible to enable compilation for it... Here is simple patch which enable compilation for Nokia N900 and fix compile errors: diff --git a/drivers/media/rc/Kconfig b/drivers/media/rc/Kconfig index b6e1311..f70d4c7 100644 --- a/drivers/media/rc/Kconfig +++ b/drivers/media/rc/Kconfig @@ -335,7 +335,7 @@ config IR_TTUSBIR config IR_RX51 tristate "Nokia N900 IR transmitter diode" - depends on OMAP_DM_TIMER && ARCH_OMAP2PLUS && LIRC && !ARCH_MULTIPLATFORM + depends on OMAP_DM_TIMER && ARCH_OMAP2PLUS && LIRC ---help--- Say Y or M here if you want to enable support for the IR transmitter diode built in the Nokia N900 (RX51) device. diff --git a/drivers/media/rc/ir-rx51.c b/drivers/media/rc/ir-rx51.c index b1e19a2..be29bd0 100644 --- a/drivers/media/rc/ir-rx51.c +++ b/drivers/media/rc/ir-rx51.c @@ -25,9 +25,9 @@ #include <linux/platform_device.h> #include <linux/sched.h> #include <linux/wait.h> +#include <linux/clk.h> -#include <plat/dmtimer.h> -#include <plat/clock.h> +#include "../../../arch/arm/plat-omap/include/plat/dmtimer.h" #include <media/lirc.h> #include <media/lirc_dev.h> @@ -208,7 +208,7 @@ static int lirc_rx51_init_port(struct lirc_rx51 *lirc_rx51) } clk_fclk = omap_dm_timer_get_fclk(lirc_rx51->pwm_timer); - lirc_rx51->fclk_khz = clk_fclk->rate / 1000; + lirc_rx51->fclk_khz = clk_get_rate(clk_fclk) / 1000; return 0; So Tony, you are author of that commit (a62a6e98c3) which broke ir-rx51 module for Nokia N900. Do you know how to fix this driver for upstream kernel? It would be great to have driver working and not to have it in this dead state... Also platform data for this driver are only in legacy board code. Support in DTS is missing, so driver (after fixing above problem) cannot be used on DT booted kernel. -- Pali Rohár pali.rohar@xxxxxxxxx
