From b050f688e1ef5b10a013d212993b54c67e22d2ec Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Thu, 19 Apr 2012 13:33:50 -0600 Subject: [PATCH] ARM: OMAP4: hwmod data: introduce fdif(face detect module) hwmod MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add hwmod data for the OMAP4 FDIF IP block. This patch also includes a change (originally from Fernando Guzman Lugo ) to set a softreset delay for the FDIF IP block: http://www.spinics.net/lists/arm-kernel/msg161874.html Signed-off-by: Ming Lei Acked-by: Benoît Cousson Cc: Fernando Guzman Lugo [paul@pwsan.com: rearranged to match script output; fixed FDIF end address to match script data; wrote trivial changelog; combined the FDIF portion of Fernando's srst_udelay patch] Signed-off-by: Paul Walmsley --- arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 79 +++++++++++++++++++++- 1 file changed, 78 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-omap2/omap_hwmod_44xx_data.c b/arch/arm/mach-omap2/omap_hwmod_44xx_data.c index 0d91dec5b4bc..eb5e98d0813a 100644 --- a/arch/arm/mach-omap2/omap_hwmod_44xx_data.c +++ b/arch/arm/mach-omap2/omap_hwmod_44xx_data.c @@ -263,7 +263,6 @@ static struct omap_hwmod omap44xx_mpu_private_hwmod = { * elm * emif1 * emif2 - * fdif * gpmc * gpu * hdq1w @@ -815,6 +814,56 @@ static struct omap_hwmod omap44xx_dss_venc_hwmod = { }, }; +/* + * 'fdif' class + * face detection hw accelerator module + */ + +static struct omap_hwmod_class_sysconfig omap44xx_fdif_sysc = { + .rev_offs = 0x0000, + .sysc_offs = 0x0010, + /* + * FDIF needs 100 OCP clk cycles delay after a softreset before + * accessing sysconfig again. + * The lowest frequency at the moment for L3 bus is 100 MHz, so + * 1usec delay is needed.
