16 years agoppc4xx: Add functionality to GPIO support
Lawrence R. Johnson [Thu, 3 Jan 2008 23:54:00 +0000 (18:54 -0500)]
ppc4xx: Add functionality to GPIO support

This patch makes two additions to GPIO support:

First, it adds function gpio_read_in_bit() to read the a bit from the
GPIO Input Register (GPIOx_IR) in the same way that function
gpio_read_out_bit() reads a bit from the GPIO Output Register
(GPIOx_OR).

Second, it modifies function gpio_set_chip_configuration() to provide
an additional option for configuring the GPIO from the
"CFG_4xx_GPIO_TABLE".

According to the 440EPx User's Manual, when an alternate output is used,
the three-state control is configured in one of two ways, depending on
the particular output.  The first option is to select the corresponding
alternate three-state control in the GPIOx_TRSH/L registers.  The second
option is to select the GPIO Three-State Control Register (GPIOx_TCR) in
the GPIOx_TRSH/L registers, and set the corresponding bit in the
GPIOx_TCR register to enable the output.  For example, the Manual
specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use
the alternate three-state control (first option), and specifies
configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output
enabled in the GPIOx_TCR register (second option).

Currently, gpio_set_chip_configuration() configures all alternate signal
outputs to use the first option.  This patch allow the second option to
be selected by setting the "out_val" element in the table entry to
"GPIO_OUT_1".  The first option is used when the "out_val" element is
set to "GPIO_OUT_0".  Because "out_val" is not currently used when an
alternate signal is selected, and because all current GPIO tables set
"out_val" to "GPIO_OUT_0" for all alternate signals, this patch should
not change any existing configurations.

AVR32: Enable interrupts at bootup

The timer code depends on the timer interrupt to keep track of the
upper 32 bits of the cycle counter. This obviously doesn't work when
interrupts are disabled the whole time.

AVR32: Fix wrong pin setup for USART3

As reported by Gerhard Berghofer:

in "gpio_enable_usart3" the correct pins for USART 3 are PB17 and PB18
instead of PB18 and PB19.

which is obviously correct. There's currently no code that uses
USART3, but custom boards may run into problems.
