| * [POWERPC] Xilinx: of_serial support for Xilinx uart 16550.John Linn2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Xilinx 16550 uart core is not a standard 16550 because it uses word-based addressing rather than byte-based addressing. With additional properties it is compatible with the open firmware 'ns16550' compatible binding. This code updates the of_serial driver to handle the reg-offset and reg-shift properties to enable this core to be used.

| * [POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms.Laurent Pinchart2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The of_serial driver queries the current-speed property and attempts to use it to register the custom_divisor property of the uart_port. However, if current-speed is not set, then this code will dereference a bad pointer. The fix is to only set custom_divisor when a current-speed property appears in the device tree.

* drivers/serial/m32r_sio.c: correct use of ! and &Julia Lawall2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337 ("wmi: (!x & y) strikes again"), a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Hirokazu Takata <takata@linux-m32r.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
