* ide: palm_bk3710: add __initdata to palm_bk3710_port_infoBhumika Goyal2017-02-271-1/+1
| | | | | | | | | | | | The object palm_bk3710_port_info of type ide_port_info is never referenced anywhere after initialization by palm_bk3710_probe. It is also passed as a parameter to ide_host_add which is called from the init function but this call doesn't store the object reference anywhere, and it only dereferences the values of the fields. Therefore add __initdata to its declaration. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | The clk API may return 0 on clk_get_rate, so we should check the result before using it as a divisor. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* Drivers: ide: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-4/+3
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton <wfp5p@virginia.edu> Cc: "David S.

* treewide: Convert uses of struct resource to resource_size(ptr)Joe Perches2011-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers.

* palm_bk3710: those registers/bitfields don't existDavid Brownell2009-04-231-49/+18
| | | | | | | | | | | | | | | | | | | | | | Bugfixes noted by checking the code against the controller documentation (TI document number SPRUE21): - Remove declarations for eight non-existent registers (!); and remove accesses to two of them. - Remove access to various non-existent bitfields in some of the registers which *do* exist (those fields must-be-zero). - Provide comment to replace bogus reset logic (removed above, it relied on non-existent bitfields). Resets require GPIO help; this driver doesn't currently know about that. With some minor cleanup: relocate a comment, avoid an extra lookup of the PIO timings.

* palm_bk3710: UDMA performance fixDavid Brownell2009-04-221-14/+12
| | | | | | | | | | | | | | | | | | | | | | Fix UDMA throughput bug: tCYC averages t2CYCTYP/2, but the code previously assumed it was the same as t2CYCTYP. (That is, it was using just one clock edge, not both.) Move the table's type declaration so it's adjacent to the table, making it more clear what those numbers mean. On one system this change increased throughput by almost 4x: UDMA/66 sometimes topped 23 MB/sec (on a drive known to do much better). On another system it was around a 10% win (UDMA/66 up to 7+ MB/sec). The difference might be caused by the ratio between memory and IDE clocks. In the system with large speedup, this was exactly 2 (as a workaround for a rev 1.1 silicon bug). The other system used a more standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch might have some issues, they're not unheard-of.
