Verify for invalid modes and unwanted flags before pass the new flags to driver. Make gpio_default_map_gpios() static. No functional changes. Improves the GPIO API description a little bit. gpio_pin_max must return the maximum supported pin number and not the total number of pins on the system. 2015-02-14T20:37:33Z Luiz Otavio O Souza loos@FreeBSD.org 2015-02-14T20:37:33Z urn:sha1:ce1028c24b1e3414eabe8c6bbb2e44271903e082 Make the GPIO children attach to the first unit available and not only to unit 0. This fix a bug where a GPIO controller could fail to attach its children (gpioc and gpiobus) if another GPIO driver attach first. 2015-02-14T19:28:26Z Luiz Otavio O Souza loos@FreeBSD.org 2015-02-14T19:28:26Z urn:sha1:48766b1f95c75aadd3a39f5710640e2f209e3118 Add a workaround needed to fix a bug of Arasan Host Controller where it may lose the contents of consecutive writes (that happens within two SD card clock cycles). This fixes the causes of instability during the SD card detection and identification on Raspberry Pi (which happens at 400 kHz and so was much more vulnerable to this issue). Remove the previous workaround which clearly can't provide the same effect. Remove stale comments about the issues with HS mode. Remove a previous workaround to limit the minimum sdhci frequency that isn't needed anymore. Remove some duplicate calls to bus_release_resource() and destroy the mutex on error cases. While here remove unnecessary includes. 2015-02-14T18:45:43Z Luiz Otavio O Souza loos@FreeBSD.org 2015-02-14T18:45:43Z urn:sha1:3dea0878a4dd7b8bdad57b9ec7ab1ac10e8f2870 Remove the '#undef DEBUG' that should not be committed. Removes unused and duplicate headers. Bring the wait limit on mailbox write to a more sane value. Fix a off-by-one bug on wait time limit. Remove extra blank line. 2015-02-14T18:37:36Z Luiz Otavio O Souza loos@FreeBSD.org 2015-02-14T18:37:36Z urn:sha1:7314359e24dd3b2d4fa8b1c49ebf7ff5117e9ae2 Make consistent use of the correct debug macros across the file. Fix the C -> K temperature conversion for the dev.cpu.0.temperature sysctl. Remove the unused temperature conversion macros. 2015-02-13T22:32:02Z Ian Lepore ian@FreeBSD.org 2015-02-13T22:32:02Z urn:sha1:bc5c4e149fb9e4282037de1c09a0382f1d8b6544 r277472, r277473, r277474, r277475, r277476, r277477, r277478, r277479, r277480, r277512, r277516: Add inline implementations of arm bus_space_read/write_N(). Revise the arm bus_space implementation to avoid dereferencing the tag on every operation to retrieve the bs_cookie value almost nothing actually uses. Use the explicit member initializer style to init the bus_space struct. Use arm/bus_space-v6.c for all armv6 systems Consolidate many identical implementations of bus_space to a single common tag and implementation shared by armv4 and armv6. Micro-optimize the new arm inline bus_space implementation by grouping all the data the inline functions access together at the start of the bus_space struct so that they all fit in a single cache line. 2015-02-13T20:38:39Z Ian Lepore ian@FreeBSD.org 2015-02-13T20:38:39Z urn:sha1:dd0d63c6caa39ed0f09dca7e180b938004b4ad46 Add defines for SDHCI 3.0 controllers. Add a new SDHCI quirk, SDHCI_QUIRK_DONT_SET_HISPD_BIT. Save the command-and-flags value into shadow register when it is written. 2015-02-13T18:16:08Z Ian Lepore ian@FreeBSD.org 2015-02-13T18:16:08Z urn:sha1:d0c3b966db9125f4a94b23ffb7130c23c069e41a Check for and handle failures of bus_dmamap_load(). Handle dma mappings with more than one segment for rpi sdhci. 2015-02-13T18:03:50Z Ian Lepore ian@FreeBSD.org 2015-02-13T18:03:50Z urn:sha1:bd4c7811db3e1780abe720031970313b597fc6c9 Store the shadow command/mode register in the softc, not a local static var. 2015-02-12T00:25:33Z Ian Lepore ian@FreeBSD.org 2015-02-12T00:25:33Z urn:sha1:c181eced071f6968a4d375c7fe5a94cc1fa3e7bd Move ofw_cpu.c to sys/dev/ofw so that it can be used by other architectures. Add driver for CPU frequency/voltage control on the Raspberry Pi. On initialization, do not use bcm_mbox_intr() to read the pending messages. This fixes the hang that happens on boot while initializing the cpufreq on Raspberry Pi.
