* | ARM: shmobile: r8a7779: setup EHCI internal bufferSergei Shtylyov2013-06-11
| | | | | | | | | | | | | | | | | | | | | | Setup the EHCI internal buffer (before EHCI driver has a chance to touch the registers) using the pre_setup() method in 'struct usb_ehci_pdata'. The patch has been tested on the Marzen board.

* | ARM: shmobile: Marzen: move USB EHCI, OHCI, and PHY devices to R8A7779 codeSergei Shtylyov2013-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB EHCI, OHCI, and common PHY are the SoC devices but are wrongly defined and registered in the Marzen board file. Move the data and code to their proper place in setup-r8a7779.c; while at it, we have to rename r8a7779_late_devices[] to r8a7779_standard_devices[] -- this seems legitimate since they are registered from r8a7779_add_standard_devices() anyway. Note that I'm deliberately changing the USB PHY platform device's 'id' field from (previously just omitted) 0 to -1 as the device is a single of its kind. Note also that the board and SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow a minimal setup of the r8a7779 SoC using a flattened device tree. In particular, configure the i2c and ethernet controllers using a flattened device tree. SCI serial controller and TMU clock source, whose drivers do not yet support configuration using a flattened device tree, are still configured using C code in order to allow booting of a board with this SoC. The ethernet controller also requires a regulator which is a board property. A sample snippet DT for the marzen board is as follows: /dts-v1/; /include/ "r8a7779.dtsi" / { fixedregulator3v3: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "fixed-3.3V"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-boot-on; regulator-always-on; }; }; &lan0 { vddvario-supply = <&fixedregulator3v3>; vdd33a-supply = <&fixedregulator3v3>; }; Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

* | ARM: delete struct sys_timerStephen Warren2012-12-24
|/ | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

| | | | | | | | | | | | | | | | | | | Fix SMP TWD boot regression on r8a7779 based platforms caused by: 4200b16 ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot r8a7779 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message.
