* [ARM] pxa: cpufreq-pxa2xx: sdram_rows detection supportPhilipp Zabel2008-12-021-3/+22
| | | | | | | | | | This patch implements Eric Miao's idea to detect the correct value of sdram_rows by inspecting the MDCNFG register settings. It is only tested on two pxa27x devices with 64MB RAM (magician and hx4700) so far. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>
* [ARM] pxa: cpufreq-pxa2xx: allow frequency table selectionMarc Zyngier2008-12-021-13/+19
| | | | | | | | | | | | | | | | | | | | Following the removal of the "->policy" usage for PXA255 in patch 459fc208abd1b365fa013c17d433dfb5b4bc1e3a (cpufreq: remove policy->governor setting in drivers initialization), this patch introduces an option (called "pxa255_turbo_table") to select either the "run" or "turbo" frequency table. It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing. Tested on an Arcom/Eurotech Viper. Signed-off-by: Marc Zyngier <maz@misterjones.org> Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Eric Miao <eric.miao@marvell.com>
* cpufreq: remove policy->governor setting in drivers initializationDominik Brodowski2008-10-151-3/+0
| | | | | | | | | | | | As policy->governor is already set to CPUFREQ_DEFAULT_GOVERNOR in the (always built-in) cpufreq core, we do not need to set it in the drivers. This fixes the sparc64 allmodconfig build failure. Also, remove a totally useles setting of ->policy in cpufreq-pxa3xx.c.
