* [PATCH] gpio_direction_output() needs an initial valueDavid Brownell2007-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | It's been pointed out that output GPIOs should have an initial value, to avoid signal glitching ... among other things, it can be some time before a driver is ready. This patch corrects that oversight, fixing - documentation - platforms supporting the GPIO interface - users of that call (just one for now, others are pending) There's only one user of this call for now since most platforms are still using non-generic GPIO setup code, which in most cases already couples the initial value with its "set output mode" request. Note that most platforms are clear about the hardware letting the output value be set before the pin direction is changed, but the s3c241x docs are vague on that topic ... so those chips might not avoid the glitches.

Note that the original AT91 GPIO calls merged the "mux pin as GPIO" and "set GPIO direction" functionality into one API call, contrary to what's specified as a cross-platform portable model.

The immediate need for such a cross-architecture API convention is to support drivers that work the same on AT91 ARM and AVR32 AP7000 chips, which embed many of the same controllers but have different CPUs. However, several other users have been reported, including a driver for a hardware watchdog chip and some handhelds.org multi-CPU button drivers.

This patch replace patch-2.6.20-rc4-spi_imx with the following changes: > Few cosmetic changes. > Function map_dma_buffers now return 0 for success and -1 for failure. > Solved a bug inside spi_imx_probe function (wrong error path). > Solved a bug inside setup function (bad undo setup for max_speed_hz). > For read-only transfers, always write zero bytes. This is almost the same as the 'BIS' version sent by Andrea, except for updating the 'DUMMY' byte so that read-only transfers shift out zeroes. That part of the API changed recently, since some half duplex peripheral chips require that semantic.

There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet.

The function name is highly misguiding (it _never_ does any checksums), the last argument is just a noise and simply expanding the call to memcpy_fromio() gives shorter and more readable source. For a lot of reasons it has almost no remaining users, so it's better to just outright kill it.

| * | | [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_userDan Williams2007-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_irqnr_preamble allows machines to take some action before entering the get_irqnr_and_base loop. On iop we enable cp6 access. arch_ret_to_user is added to the userspace return path to allow individual architectures to take actions, like disabling coprocessor access, before the final return to userspace. Per Nicolas Pitre's note, there is no need to cp_wait on the return to user as the latency to return is sufficient.

| * | | [ARM] 4184/1: iop: cp6 access handler (undef_hook)Dan Williams2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable svc access to cp6 via an undefined instruction hook. Do not enable access for usr code. This patch also makes iop13xx select PLAT_IOP, this requires a small change to drivers/i2c/busses/i2c-iop3xx.c. Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop Per Nicolas Pitre's note, the cp_wait is skipped since the latency to return to the faulting function is longer than cp_wait.

| * | | [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static rangesDan Williams2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a custom ioremap implementation for iop3xx. This saves establishing new mappings. It also cleans up the PCI IO resource to be a physical address rather than a virtual address as Russell pointed out on the original iop13xx port.

This patch enables revC by default and adds a config option for building the kernel for the revB platform. Since the SCU base address was hard-coded in the proc-v6.S file (and only valid for RealView/EB revB), this patch also adds a more generic support for defining the SCU information.
