2016-02-11arm: lpc32xx: switch to common clock frameworkVladimir Zapolskiy1-1284/+0
The change switches NXP LPC32xx platforms to LPC32xx clock driver powered by common clock framework, this obsoletes mach-lpc32xx/clock.o legacy clock driver and thus it is removed. Legacy timer driver mach-lpc32xx/timer.o strictly depends on legacy clock support, but fortunately an existing LPC32xx clock source and clock event driver completely replaces it, and thus it can be removed as well. Noticeably platform UART driver directly operates on LPC32xx source control block registers, remove this dependency to avoid overlapping with common clock framework driver, also this guarantees that UART is working expectedly.

2015-05-06ARM: lpc32xx: convert to use clkdev_add_table()Russell King1-4/+1
We have always had an efficient way of registering a table of clock lookups - it's called clkdev_add_table(). However, some people seem to really love writing inefficient and unnecessary code. Convert LPC32xx to use the correct interface. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-07-01ARM: LPC32xx: Cleanup USB clock initAlexandre Pereira da Silva1-1/+67
Move most of usb clock initialization from lpc32xx_udc and ohci-nxp to clock.c. Also adds ohci clocks and otg clocks. Signed-off-by: Alexandre Pereira da Silva <aletes.xgr@gmail.com> Signed-off-by: Roland Stigge <stigge@antcom.de>
2012-07-01ARM: LPC32xx: Remove wrong re-initialization of MMC clock registerRoland Stigge1-7/+3
This patch fixes a bug, (wrongfully) resetting the value of LPC32XX_CLKPWR_MS_CTRL back to its initial contents (after careful setup). This was discovered only with a board/bootloader combination (EA3250) where the contents of the respective register wasn't already at the correct value on Linux boot.

2012-03-29ARM: LPC32xx: clock.c: Fix lpc-eth clock referenceRoland Stigge1-1/+1
During a complex merge for v3.4, one line of the commit c20b909be9ba27173294a52d08cab293ec030a2c ("ARM: LPC32xx: Ethernet support") was reverted wrongly ("lpc-eth.0" -> "lpc-net.0") while the other conflicts were merged correctly. This patch re-applies the clock name "lpc-eth.0". Signed-off-by: Roland Stigge <stigge@antcom.de> Signed-off-by: Olof Johansson <olof@lixom.net>
2012-03-27Merge branch 'fixes-non-critical' into next/drivers2Olof Johansson1-2/+2
fixes-non-critical has already been merged upstream, and there are a handful of annoying context conflicts that it makes sense to resolve before sending up. Part of this is because there was parallel development going on between more urgent fixes and general driver fixups, it should settle down once the lpc32xx platform reaches a more steady state.

2012-03-13ARM: LPC32xx: Ethernet supportRoland Stigge1-1/+1
This patch adds ethernet support to the LPC32xx ARM architecture. The actual driver in drivers/net is contained in a separate patch. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2012-03-13ARM: LPC32xx: USB SupportRoland Stigge1-24/+63
This patch adds OHCI support to the LPC32xx ARM platform. Besides the trivial addition of platform "usb-ohci" support, fixes for the USB PLL have been added to arch/arm/mach-lpc32xx/clock.c, ported from NXP's lpclinux.com. (This is the mach-lpc32xx specific part, the USB subsystem specific changes are in a separate patch for the USB maintainers.) Signed-off-by: Roland Stigge <stigge@antcom.de>

2012-02-09ARM: LPC32xx: clock.c: Clock registration fixesRoland Stigge1-3/+3
This patch adjusts the clock registration list, ported from the latest version of Kevin Wells' latest version of clock.c: i2s0_ck, i2s1_ck and dev:mmc0 have NULL pointers associated as the .dev_id and .con_id, respectively. The old values were not useful. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Kevin Wells <kevin.wells@nxp.com> Signed-off-by: Olof Johansson <olof@lixom.net>

This patch fixes the jiffies wrapping bug in clock.c. It corrects the timeout computation based on jiffies, uses time_before() for correct wrapping handling and replaces a binary "&" which should really be a logical "&&" in a truth expression.

2012-02-09ARM: LPC32xx: clock.c: Fix mutex lock issuesRoland Stigge1-30/+11
This patch fixes the mutex issue in clock.c, as done in Kevin Wells' original driver update: In some cases, the clock drivers could grab a mutex twice in an improper context. This patch changes the mutex mechanism to a simple irq lock/unlock mechanism and removes un-needed locks from some functions.
