From 4311d9654c66b7cc7147035b8ec74f41ddffa650 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 23 Oct 2014 13:18:53 +0200 Subject: [PATCH] ARM: shmobile: armadillo800eva legacy: Add missing A3SP pm domain devices MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 802a5639aa7041b2 ("ARM: shmobile: r8a7740: add A3SP pm domain support") added the A3SP power domain, but forgot to hook up the TPU, SDHI0/1, and MMCIF hardware blocks. Note: As the default PM QoS latency constraint for SDHI is only 100 µs (cfr. commit c419e611c3c59c0e ("tmio_mmc / PM: Use PM QoS latency constraint"), while DEFAULT_DEV_LATENCY_NS is 250000, suspend fails with -EBUSY, unless the constraint is increased first to more than 500 µs using e.g. echo 501 > /sys/devices/platform/sh_mobile_sdhi.0/power/pm_qos_resume_latency_us Signed-off-by: Geert Uytterhoeven Signed-off-by: Simon Horman --- arch/arm/mach-shmobile/board-armadillo800eva.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-shmobile/board-armadillo800eva.c b/arch/arm/mach-shmobile/board-armadillo800eva.c index e70983534403..4bc202dd828a 100644 --- a/arch/arm/mach-shmobile/board-armadillo800eva.c +++ b/arch/arm/mach-shmobile/board-armadillo800eva.c @@ -1234,8 +1234,11 @@ static void __init eva_init(void) static struct pm_domain_device domain_devices[] __initdata = { { "A4LC", &lcdc0_device }, { "A4LC", &hdmi_lcdc_device }, + { "A3SP", &pwm_device }, + { "A3SP", &sdhi0_device }, + { "A3SP", &sh_mmcif_device }, }; - struct platform_device *usb = NULL; + struct platform_device *usb = NULL, *sdhi1 = NULL; regulator_register_always_on(0, "fixed-3.3V", fixed3v3_power_consumers, ARRAY_SIZE(fixed3v3_power_consumers), 3300000); @@ -1304,6 +1307,7 @@ static void __init eva_init(void) platform_device_register(&vcc_sdhi1); platform_device_register(&sdhi1_device); + sdhi1 = &sdhi1_device; } @@ -1324,6 +1328,8 @@ static void __init eva_init(void) ARRAY_SIZE(domain_devices)); if (usb) rmobile_add_device_to_domain("A3SP", usb); + if (sdhi1) + rmobile_add_device_to_domain("A3SP", sdhi1); r8a7740_pm_init(); } -- 2.34.1
