Subject: USB & hwmon on am33xx
Date: Tue, 09 Jul 2013 18:32:57 +0200 [thread overview]
Message-ID: <51DC3B39.6000104@linutronix.de> (raw)
Hi Paul,
I'm slowly losing my mind with hwmod.
arch/arm/boot/dts/am33xx.dtsi has the ti,musb-am33xx node.
That one has "usb_otg_hs" as hwmod property.
The entry for it arch/arm/mach-omap2/omap_hwmod_33xx_data.c uses
AM33XX_CM_PER_USB0_CLKCTRL_OFFSET (0x1c) as the clk. The TRM only
mentions this one, i.e. no USB1.
Now I have the following logical devices here:
- usb0 instance + its glue code for irqs
- usb1 instance + its glue code for irqs
- two phy instances, one for USB0 and one USB1
- one dma engine which serves both usb instances.
Shouldn't I have for each device (usb0/1, phy0/1, dma) a hwmod entry?
Or is it enough to use the same entry for each device?
Sebastian
