| | | | | | | | | | | | | | | | | | In commit f0fba2ad (ASoC: multi-component - ASoC Multi-Component Support), the name of the ak4104 codec driver was changed without amending the platform code which uses it as well.

| * ARM: pxa: fix gpio_to_chip() clash with gpiolib namespaceLinus Walleij2011-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | The PXA platform code has a static inline helper called gpio_to_chip which clashes with the gpiolib namespace if we try to expose the function with the same name from gpiolib, and it's still confusing even if we don't do that. So rename it to gpio_to_pxachip().

* | genirq: replace irq_gc_ack() with {set,clr}_bit variants (fwd)Simon Guinot2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression introduced by e59347a "arm: orion: Use generic irq chip". Depending on the device, interrupts acknowledgement is done by setting or by clearing a dedicated register. Replace irq_gc_ack() with some {set,clr}_bit variants allows to handle both cases. Note that this patch affects the following SoCs: Davinci, Samsung and Orion. Except for this last, the change is minor: irq_gc_ack() is just renamed into irq_gc_ack_set_bit(). For the Orion SoCs, the edge GPIO interrupts support is currently broken. irq_gc_ack() try to acknowledge a such interrupt by setting the corresponding cause register bit. The Orion GPIO device expect the opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used. Tested on Network Space v2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The recently modified nand buswitth configuration is not aligned with board reality: the double footprint on boards is always populated with 8bits buswidth nand flashes. So we have to consider that without particular configuration the 8bits buswidth is selected by default. Moreover, the previous logic was always using !board_have_nand_8bit(), we change it to a simpler: board_have_nand_16bit().

| * | xen/pci: Use the INT_SRC_OVR IRQ (instead of GSI) to preset the ACPI SCI IRQ.Konrad Rzeszutek Wilk2011-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the past we would use the GSI value to preset the ACPI SCI IRQ which worked great as GSI == IRQ: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level) While that is most often seen, there are some oddities: ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 20 low level) which means that GSI 20 (or pin 20) is to be overriden for IRQ 9. Our code that presets the interrupt for ACPI SCI however would use the GSI 20 instead of IRQ 9 ending up with: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=20 xen: acpi sci 20 .. snip.. calling acpi_init+0x0/0xbc @ 1 ACPI: SCI (IRQ9) allocation failed ACPI Exception: AE_NOT_ACQUIRED, Unable to install System Control Interrupt handler (20110413/evevent-119) ACPI: Unable to start the ACPI Interpreter as the ACPI interpreter made a call to 'acpi_gsi_to_irq' which got nine. It used that value to request an IRQ (request_irq) and since that was not present it failed. The fix is to recognize that for interrupts that are overriden (in our case we only care about the ACPI SCI) we should use the IRQ number to present the IRQ instead of the using GSI. End result is that we get: xen: sci override: global_irq=20 trigger=0 polarity=1 xen: registering gsi 20 triggering 0 polarity 1 xen: --> pirq=20 -> irq=9 (gsi=9) xen: acpi sci 9 which fixes the ACPI interpreter failing on startup.

Also remove the clock-frequency property from the wm8776 node, because the clock is enabled only if U-Boot enables it, and U-Boot will set the property if the clock is enabled. A future version of the P1022DS audio driver will configure the clock itself, but for now, the driver should not be told that the clock is running when it isn't. Also fix the FIFO depth to 15, instead of 16. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

For example, if just only one clock source is defined even though there are two clock sources for UART, the serial driver does not set proper clock up. Of course, it is problem. So this patch changes the condition of comparison to avoid useless setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means selection of source clock is not required. In addition, since the Exynos4210 has only one clock source for UART this patch adds the flag into its common_init_uarts().

But, it's not defined in linux/mmzone.h but defined in /arch/???/include/mmzone.h which is included only under CONFIG_NEED_MULTIPLE_NODES=y. Then, we see mm/page_cgroup.c: In function 'page_cgroup_init': mm/page_cgroup.c:308: error: implicit declaration of function 'node_start_pfn' mm/page_cgroup.c:309: error: implicit declaration of function 'node_end_pfn' So, fixiing page_cgroup.c is an idea... But node_start_pfn()/node_end_pfn() is a very generic macro and should be implemented in the same manner for all archs. (m32r has different implementation...) This patch removes definitions of node_start/end_pfn() in each archs and defines a unified one in linux/mmzone.h. It's not under CONFIG_NEED_MULTIPLE_NODES, now. A result of macro expansion is here (mm/page_cgroup.c) for !NUMA start_pfn = ((&contig_page_data)->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (&contig_page_data); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); for NUMA (x86-64) start_pfn = ((node_data[nid])->node_start_pfn); end_pfn = ({ pg_data_t *__pgdat = (node_data[nid]); __pgdat->node_start_pfn + __pgdat->node_spanned_pages;}); Changelog: - fixed to avoid using "nid" twice in node_end_pfn() macro.
