2009-02-04Blackfin arch: cplb mananger: use a do...while loop rather than a for loopMike Frysinger
use a do...while loop rather than a for loop to get slightly better optimization and to avoid gcc "may be used uninitialized" warnings ... we know that the [id]cplb_nr_bounds variables will never be 0, so this is OK Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>

2009-02-04Blackfin arch: reset POLAR setting when acquiring a gpio for the first timeMichael Hennerich
when requesting a GPIO for the first time, the POLAR setting is not set to a sane state. this can lead to indeterminate behavior that cannot be resolved without an explicit write to the Blackfin port POLAR register. when requesting a GPIO for the first time via gpio_request(), the POLAR setting for the GPIO in question should be set to sane state. this should occur if the GPIO has not been allocated in any other way. some examples: - when doing something like "request_irq(); gpio_request();" on the same GPIO, the POLAR setting should not be reset. - when doing "gpio_request(); gpio_request();" on the same GPIO, the POLAR setting should be reset only the first time and not the second.

2009-02-02mmc: Add a MX2/MX3 specific SDHC driverSascha Hauer
This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically the same as in the MX1, but unlike the MX1 controller the MX2 controller just works as expected. Since the MX1 driver has more workarounds for bugs than anything else I had no success with supporting MX1 and MX2 in a sane way in one driver.

2009-02-02powerpc: Fix oops on some machines due to incorrect pr_debug()Benjamin Herrenschmidt
Recently, a patch left DEBUG enabled in the powerpc common PCI code, resulting in an old bug in a pr_debug() statement to show up and cause a NULL dereference on some machines. This fixes the pr_debug() statement and reverts to DEBUG not being force-enabled in that file. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
