Otherwise pinctrl won't work. Because of silicon errata for some dm814x
versions, let's also keep bit 18 out of the function-mask and rely on
the bootloader configuration for bit 18  as suggested by
Matthijs van Duin <matthijsvanduin@gmail.com>.

Devices with that need to use bit 18 can override the function-mask in
the board specific dts file if really needed.

The control module is at offset 0x14000 with size 0x20000, not 0x16000.
This causes the pinctrl driver to not work.

Let's also fix the comments related to the TRM "L4LS Instance Summary"

Although we have hp t410 booting, I noticed that dm814x-evm does not boot
after I got one. This is because we don't have the clocks yet configured
properly. Let's start configuring proper clocks starting with the system
timers and clocks that work with existing mux and divider clock drivers.

Note that the oscillator speed register is different from am335x, dm814x
has only one bit that shows the BTMODE[6] at CONTROL_STATUS[21].

Also note that this only gets the system timers working with the defined
clocks. The PLL clocks are still missing and and the devices may or may
not work depending on what the bootloader has enabled.

Following that I did miss Stephen's messages about the build failure in

Signed-off-by: Eric Anholt <eric@anholt.net>
Acked-by: Stephen Warren <swarren@wwwdotorg.org>

This will give us the ability to set the pixel and HDMI state machine
clocks for the VC4 KMS driver, change the CPU frequency, and
potentially gate clocks in the future (once we also write a power
domain driver).  It also gives the uart an explicit clock reference,
so that we don't need to change the physical addresses of the old
fixed clk_bcm2835.c clocks for Raspberry Pi 2 port.

Two clocks get their frequencies updated as a result of this.  One is
uart's apb_pclk, which was previously accidentally grabbing the fixed
uart0_pclk due to the apb_pclk not having clk_register_clkdev()
called.  The uart doesn't seem to do anything with apb_pclk other than
make sure it's on, so that appears safe (also, as far as I can see,
the apb clock is actually the same as the VPU clock).  The other is
EMMC, which according to the docs was supposed to be in the 50-100Mhz
range, but it turns out the firmware needed to change to running it at
the 250Mhz core clock speed to avoid a bug in clock domain crossing.

Additionally, anything using BCM2835_CLOCK_VPU will now have a correct
clock rate if the user configures the boot-time core clock speed using
config.txt.

only works when ldo3 is set to 2.8 volt, otherwise i2c1 gets stuck, so
for now we mark i2c1 as failed.

It has a pixcir,pixcir_tangoc compatible touchscreen attached to i2c2 addr

to be driven low before the touchscreen will work. Before we can enable
