| * ktest: Update documentation on config_bisectSteven Rostedt (Red Hat)2014-04-231-38/+27
| | | | | | | | | | | | | | | | | | | | With the more robust config_bisect, the documentation is out of date and needs to be updated. The new rewrite allows for finding missing configs and such, and is much more robust to use. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Add the config bisect manual backSteven Rostedt (Red Hat)2014-04-231-1/+7

| * ktest: Remove unused functionsSteven Rostedt (Red Hat)2014-04-231-62/+1
| | | | | | | | | | | | | | | | | | | | | | After the rewrite of the config bisect, there were several unused functions that can be removed. One of the unused functions printed out the failed config nicer than what the rewrite did, so I kept that and used it to output the bad config. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * ktest: Put back in the CONFIG_BISECT_CHECKSteven Rostedt (Red Hat)2014-04-231-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | The new rewrite left out the CONFIG_BISECT_CHECK, which allows the user to test that their "bad" config still is bad and their "good" config still is good. This is especially important as the configs are passed through a "make oldconfig" to update them with the lastest kernel. Things could change that causes a bad config to work, or a good config to break. The check is done after the configs have run through the oldconfig processing.

| * ktest: Rewrite the config-bisect to actually workSteven Rostedt (Red Hat)2014-04-231-226/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I never liked the way config-bisect worked. I would assume the bad config had some config that broke the system. But it would not work if the bad config just happened to be missing something that the good config had. I rewrote the config-bisect to do this properly. It does a diff of the two configs, and sets half of the configs that are in one and not the other. The way it works is that when it "sets", it really just makes one copy what the other has. That is, a "set" can be setting a: # CONFIG_FOO is not set Basically, it looks at the differences between the two files and makes them similar until it comes down to one config that makes it work or not work depending on if it is set or not. Note, if more than one config change makes the bad config not work, it will only find one of them. But this is true with all bisect logic. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cleanup for improving readability as follows. - Initialize $ktest_config at its definition. - Put parentheses around the `config-file' argument in the usage message because it's a optional one. - Rename get_ktest_config{,s} to more descriptive get_mandatory_config{,s}.

| | | | | | | | | | | | | | | | | | | | | | | | If we'd like to set the redirect target file of run_command(), we should define $redirect before calling this function and should undef it after calling this function. Since it's user-unfriendly, add 2nd parameter of run_command() for this purpose.

The idea is to have an instance of "struct flexgen" per output clock. It represents the clock cross bar (by a mux element), and the pre and final dividers (using dividers and gates elements).

However, the rest of sunxi clock drivers use bitmaps for this purpose. This patch modifies sun6i-apb0-gates to use bitmaps as well, to be consistent with the sunxi platform. Also add the missing call to clk_register_clkdev, so system clock lookups will work. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
| | * | | | clk: sunxi: Fix gate indexing for sun6i-a31-apb0-gatesChen-Yu Tsai2014-07-071-1/+5

However, the driver passes the number of gates registered in clk_data->clk_num, which of_clk_src_onecell_get uses to recognize the range of valid indices a consumer can use. This patch makes the driver pass the maximum gate index + 1, so of_clk_src_onecell_get does not complain about indices greater than gates registered. This was tested on the A23 SoC, which has a similar APB0 clock, but has holes for gates to removed IP blocks.
