* 'omap-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6: (26 commits)
  OMAP2 clock: dynamically allocate CPUFreq frequency table
  OMAP clock/CPUFreq: add clk_exit_cpufreq_table()
  OMAP2xxx OPP: clean up comments in OPP data
  OMAP2xxx clock: clk2xxx.c doesn't compile if CPUFREQ is enabled
  OMAP1 clock: remove __initdata from struct clk_functions to prevent crash
  OMAP1 clock: Add missing clocks for OMAP 7xx
  OMAP clock: remove incorrect EXPORT_SYMBOL()s
  OMAP3 clock: Add capability to change rate of dpll4_m5_ck
  OMAP3 clock: McBSP 2, 3, 4 functional clock parent is PER_96M_FCLK, not CORE_96M_FCLK
  OMAP3: clock: add clockdomains for UART1 & 2
  OMAP2420 IO mapping: move IVA mapping virtual address out of vmalloc space
  OMAP2xxx IO mapping: mark DSP mappings as being 2420-only
  ARM: OMAP3: PM: Fix the Invalid CM_CLKSTCTRL reg access.
  OMAP2: remove duplicated #include
  omap3: EVM: Choose OMAP_PACKAGE_CBB
  omap3: Fix booting if package is uninitialized
  omap3: add missing parentheses
  omap3: add missing parentheses
  omap2/3: ZOOM: Correcting key mapping for few keys
  omap2/3: make serial_in_override() address the right uart port

+Description
+-----------
+
+This driver implements support for the Texas Instruments amc6821 chip.
+The chip has one on-chip and one remote temperature sensor and one pwm fan
+regulator.
+The pwm can be controlled either from software or automatically.
+
+The driver provides the following sensor accesses in sysfs:
+

+temp1_min              rw      "
+temp1_max              rw      "

+temp2_min              rw      "
+temp2_max              rw      "

+temp2_min_alarm                ro      "

+                               0 degree C to 124 degree C in steps of
+                               4 degree C. Read it out after writing to get
+                               the actual value.
+temp1_auto_point3_temp rw      Above this temperature fan runs at maximum
+                               speed. It can go from temp1_auto_point2_temp.
+                               It can only have certain discrete values
+                               which depend on temp1_auto_point2_temp and
+                               pwm1_auto_point2_pwm. Read it out after
+                               writing to get the actual value.
+
+temp2_auto_point1_temp rw      Must be between 0 degree C and 63 degree C and
+                               it defines the passive cooling temperature.
+                               Below this temperature the fan stops in
+                               the closed loop mode.
+temp2_auto_point2_temp rw      The low-temperature limit of the proportional
+                               range. Below this temperature
+                               pwm1 = pwm1_auto_point2_pwm. It can go from
+                               0 degree C to 124 degree C in steps
+                               of 4 degree C.
+
+temp2_auto_point3_temp rw      Above this temperature fan runs at maximum
+                               speed. It can only have certain discrete
+                               values which depend on temp2_auto_point2_temp
+                               and pwm1_auto_point2_pwm. Read it out after

+
+Module parameters
+-----------------
+
+If your board has a BIOS that initializes the amc6821 correctly, you should
+load the module with: init=0.
+
+If your board BIOS doesn't initialize the chip, or you want
+different settings, you can set the following parameters:
+init=1,
+pwminv: 0 default pwm output, 1 inverts pwm output.
