From mboxrd@z Thu Jan 1 00:00:00 1970 From: tony@atomide.com (Tony Lindgren) Date: Thu, 15 Dec 2011 13:41:09 -0800 Subject: [PATCH 1/9] ARM: OMAP2+: mux: add wakeup-capable hwmod mux entries to dynamic list In-Reply-To: <20111215213609.26632.43406.stgit@dusk> References: <20111215213358.26632.44165.stgit@dusk> <20111215213609.26632.43406.stgit@dusk> Message-ID: <20111215214109.GX32251@atomide.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org * Paul Walmsley [111215 13:05]: > omap_hwmod_mux() currently only iterates through the dynamic pad list. > This list currently only consists of pads with the > OMAP_DEVICE_MUX_REMUX flag set. > > Subsequent patches in this series will cause hwmod mux entries with > the OMAP_DEVICE_MUX_WAKEUP flag set to be changed dynamically, to > control hwmod I/O ring wakeup. For this to work correctly, hwmod mux > entries with the OMAP_DEVICE_MUX_WAKEUP flag set must also be added to > the dynamic pad list. So this patch modifies omap_hwmod_mux_init() to > do so. > > Signed-off-by: Paul Walmsley > Cc: Tony Lindgren > Cc: Tero Kristo > Cc: Govindraj R Acked-by: Tony Lindgren > --- > arch/arm/mach-omap2/mux.c | 6 ++++-- > 1 files changed, 4 insertions(+), 2 deletions(-) > > diff --git a/arch/arm/mach-omap2/mux.c b/arch/arm/mach-omap2/mux.c > index 655e948..a474c81 100644 > --- a/arch/arm/mach-omap2/mux.c > +++ b/arch/arm/mach-omap2/mux.c > @@ -306,7 +306,8 @@ omap_hwmod_mux_init(struct omap_device_pad *bpads, int nr_pads) > pad->idle = bpad->idle; > pad->off = bpad->off; > > - if (pad->flags & OMAP_DEVICE_PAD_REMUX) > + if (pad->flags & > + (OMAP_DEVICE_PAD_REMUX | OMAP_DEVICE_PAD_WAKEUP)) > nr_pads_dynamic++; > > pr_debug("%s: Initialized %s\n", __func__, pad->name); > @@ -331,7 +332,8 @@ omap_hwmod_mux_init(struct omap_device_pad *bpads, int nr_pads) > for (i = 0; i < hmux->nr_pads; i++) { > struct omap_device_pad *pad = &hmux->pads[i]; > > - if (pad->flags & OMAP_DEVICE_PAD_REMUX) { > + if (pad->flags & > + (OMAP_DEVICE_PAD_REMUX | OMAP_DEVICE_PAD_WAKEUP)) { > pr_debug("%s: pad %s tagged dynamic\n", > __func__, pad->name); > hmux->pads_dynamic[nr_pads_dynamic] = pad; > >
