2013-06-04cpufreq: rename index as driver_data in cpufreq_frequency_tableViresh Kumar1-4/+4
The "index" field of struct cpufreq_frequency_table was never an index and isn't used at all by the cpufreq core. It only is useful for cpufreq drivers for their internal purposes. Many people nowadays blindly set it in ascending order with the assumption that the core will use it, which is a mistake. Rename it to "driver_data" as that's what its purpose is. All of its users are updated accordingly. [rjw: Changelog] Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Rafael J.

Remove specifying mmc controller IP version information via platform data, instead specify device name so that driver derives it from platform_device_id table. Also change the clock node name to match the changed dev_id. Tested on da850-evm to make sure driver loads without clk_get failures.

AM18x/DA850/OMAP-L138 SoCs have variants that can operate at a maximum of 456 MHz at 1.3V operating point. Also the 1.2V operating point has a variant that can support a maximum of 375 MHz. This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz) to the list of DA850 OPPs. Not all silicon is qualified to run at higher speeds and unfortunately the maximum speed the chip can support can only be determined from the label on the package (not software readable). Because of this, we depend on the maximum speed grade information to be provided to us in some board specific way. The board informs the maximum speed grade information by setting the da850_max_speed variable. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

Current cpufreq code does not consider errors that can occur while changing voltage. Code to increase CPU frequency goes ahead even in the case the regulator has failed to increase the voltage. This leads to hard error since lower voltages cannot support increased frequency. Prevent this by not increasing frequency in case increasing voltage is not successful. Also, do not lower the voltage if changing the cpu frequency has failed for some reason. Note that we do not return error on failure to decrease voltage as that is not a hard error.

2010-08-05davinci: da8xx: sparse cleanup: remove duplicate entries in irq prioritiesSekhar Nori1-25/+0
This patch helps get rid of the following sparse warnings of the type: CHECK arch/arm/mach-davinci/da830.c arch/arm/mach-davinci/da830.c:1026:3: warning: Initializer entry defined twice arch/arm/mach-davinci/da830.c:1027:3: also defined here coming from the irq priorities array init. Apart from one instance of genuinie repetition, most are are instances of multiple #defines of the same interrupt number. I have not removed the multiple definitions from the irq.h file in the hope that someone might decide to use them as shared interrupts at some point of time. The priority initialization however needs to be done only once and hence has been corrected. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-13Davinci: iotable based ioremap() interceptionCyril Chemparathy1-2/+2
This patch allows for a more flexible ioremap() interception based on iotable contents. With this patch, the ioremap() interception code can properly translate addresses only after davinci_soc_info has been initialized. Consequently, in soc-specific init functions, davinci_common_init() has to happen before any ioremap() attempts. The da8xx init sequence has been suitably modified to meet this restriction.

2010-05-13Davinci: pinmux - use ioremap()Cyril Chemparathy1-2/+1
This patch modifies the pinmux implementation so as to ioremap() the pinmux register area on first use. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-13Davinci: aintc/cpintc - use ioremap()Cyril Chemparathy1-1/+1
This patch implements the following: - interrupt initialization uses ioremap() instead of passing a virtual address via davinci_soc_info. - machine definitions directly point to cp_intc_init() or davinci_irq_init() - davinci_intc_type and davinci_intc_base now get initialized in controller specific init functions instead of davinci_common_init() - minor fix in davinci_irq_init() to use intc_irq_num instead of DAVINCI_N_AINTC_IRQ Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-13Davinci: psc - use ioremap()Cyril Chemparathy1-4/+1
This patch modifies the psc and clock control code to use ioremap()ed registers. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-13Davinci: timer - use ioremap()Cyril Chemparathy1-4/+4
This patch eliminates IO_ADDRESS() usage for Davinci timer definitions. The timer code has correspondingly been modified to ioremap() MMRs instead. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-13Davinci: jtag_id - use ioremap()Cyril Chemparathy1-2/+1
This patch replaces the jtag id base info in davinci_soc_info with a physical address which is then ioremap()ed within common code. This patch (in combination with a similar change for PSC) will allow us to eliminate the SYSCFG nastiness in DA8xx code.

2010-05-13Davinci: gpio - use ioremap()Cyril Chemparathy1-1/+1
This patch modifies the gpio_base definition in davinci_soc_info to be a physical address, which is then ioremap()ed by the gpio initialization function. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
