RTC module The RTC module is physically present on the AM438x SoC used on AM43X-EPOS-EVM, but it is permanently disabled. A secure RTC is used instead on these devices, where needed. . Hence adding it selectively using a seprate list to get RTC Module functional on the other am43x SoCs used on am437x-gp-evm and am437x-sk-evm. Signed-off-by: Keerthy <j-keerthy@...com> --- No Public TRM is available for AM438x SoC as of now. arch/arm/mach-omap2/omap_hwmod_43xx_data.c | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-omap2/omap_hwmod_43xx_data.c b/arch/arm/mach-omap2/omap_hwmod_43xx_data.c index e97a894..fcffaf8 100644 --- a/arch/arm/mach-omap2/omap_hwmod_43xx_data.c +++ b/arch/arm/mach-omap2/omap_hwmod_43xx_data.c @@ -1020,9 +1020,21 @@ static struct omap_hwmod_ocp_if *am43xx_hwmod_ocp_ifs[] __initdata = { NULL, }; +static struct omap_hwmod_ocp_if *am43xx_rtc_hwmod_ocp_ifs[] __initdata = { + &am33xx_l4_wkup__rtc, + NULL, +}; + int __init am43xx_hwmod_init(void) { + int ret; + omap_hwmod_am43xx_reg(); omap_hwmod_init(); - return omap_hwmod_register_links(am43xx_hwmod_ocp_ifs); + ret = omap_hwmod_register_links(am43xx_hwmod_ocp_ifs); + + if (!(of_machine_is_compatible("ti,am438x"))) + ret = omap_hwmod_register_links(am43xx_rtc_hwmod_ocp_ifs); + + return ret; } -- 1.9.1
