PDMA controllers when instantiated from device tree are registered using amba_device_register(). The registration process enables clock to the controllers to read the peripheral id of the PDMA amba device. In case of Exynos4, the clocks to the PDMA controllers are named as 'dma' but amba_device_register() looks up the clock using the name 'apb_pclk'. Hence, alias clocks with name 'apb_pclk' clock are created for clocks with name 'dma'. Signed-off-by: NThomas Abraham <thomas.abraham@linaro.org> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

Instead of using clock names supplied in platform data, use a generic clock name 'clk_uart_baud' to look up clocks. The platform code should register clocks with the name 'clk_uart_baud' which can be used by the baud rate generator. The clock lookup and selection of the best clock as baud rate clock is reworked. Platform code can specify the clocks that can be used as source for the baud clock (as supported previously by passing names of clocks). A new member is added to the platform data 'clk_sel' which holds a bit-field value with each bit representing a baud source clock. If a bit at any bit position is set, that clock is looked up to participate in the selection of the baud clock source.

s3c2440 uses fclk/n (fclk divided by n) clock as one of the possible clocks used to generate the baud rate clock. The divider 'n' in this case can be logically represented outside of the uart controller. This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to represent the fclk/n clock in the platform code. This clock provides a get_rate callback that checks the UCON0/1/2 registers to determine the clock rate. The samsung uart driver would receive the "fclk_n" clock name as one of the possible baud rate clock options and the driver need not determine clock rate of fclk/n.

The timer irqs statically mapped from linux irq numbers 11 to 15 are moved to the end of the statically mapped linux irq space. The GIC PPI and SPI interrupts are relocated to start from 16 and 32 of the linux irq space. This is a required to add device tree support for GIC and Interrupt combiner for EXYNOS4. A new macro 'IRQ_TIMER_BASE' specifies a platform specific base of the linux virq number for the timer interrupts. For exynos4, this base is set to end of the linux virq space. For the other S5P platforms, the existing base '11' is retained. Signed-off-by: NThomas Abraham <thomas.abraham@linaro.org> Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

d312ae87 "xen: use maximum reservation to limit amount of usable RAM" clamped the total amount of RAM to the current maximum reservation. This is correct for dom0 but is not correct for guest domains. In order to boot a guest "pre-ballooned" (e.g. with memory=1G but maxmem=2G) in order to allow for future memory expansion the guest must derive max_pfn from the e820 provided by the toolstack and not the current maximum reservation (which can reflect only the current maximum, not the guest lifetime max). The existing algorithm already behaves this correctly if we do not artificially limit the maximum number of pages for the guest case. For a guest booted with maxmem=512, memory=128 this results in: [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] Xen: 0000000000000000 - 00000000000a0000 (usable) [ 0.000000] Xen: 00000000000a0000 - 0000000000100000 (reserved) -[ 0.000000] Xen: 0000000000100000 - 0000000008100000 (usable) -[ 0.000000] Xen: 0000000008100000 - 0000000020800000 (unusable) +[ 0.000000] Xen: 0000000000100000 - 0000000020800000 (usable) ...
